This has only started happening since the update with scratchpads. If you click on the 3 dots to the right side of the pinned charts, as per usual the trash symbol apears on each chart, but clicking the trash symbol does nothing, you cannot delete individual charts.
In case I haven’t explained well, here is a video:

HI Charles,
Please confirm you are running Navigraph Charts V 8.42.0 and using a mouse click. Check you have Sync Current Flight unselected.
Maybe try redownload/Reinstall and run Navigraph Charts
Cheers
Ian
Hi Ian
Version is 8.42.0 :-
Mouse click - no, since using Navigraph Charts the last 16 years I have a touch-screen monitor connected to my PC - this acts as my EFB. I don’t have any keyboards/mice as it is a replica cockpit. I hope this has not changed as I don’t think it would be a good move for realism to cater only to keyboards/mice
In the meantime I’ll try re-installing and report back
I have just re-installed Charts, it seems to work with mouse click but not with my touchscreen. If I select to delete an individual chart using touchscreen, it just moves to Flight view with overlay, here is a video below.
I have charts on a client pc separate from my MSFS PC (the latter has simlink), the client pc has a touchscreen monitor as mentioned
Hi Ian, sorry to chase, I am only doing so because it is having a big impact, I have never had a serious issue like this in 16 years as a Navigraph user, it is certainly a huge regression rather than an advance not being able to use touch-screen, after all the real thing uses that and isn’t the whole point the realism?
Please can you let me know if anything can be done here?
Many thanks
Charles
Is the touch screen PC running the latest non beta Windows 11?
If you run other non Navigraph apps on the touchscreen PC, do you get similar behaviour?
Windows display scaling / DPI issue
Navigraph Charts (Electron app) can sometimes mis-map touch coordinates when Windows display scaling is high.
Try this:
If that fixes it, you can try 125% instead of 150–200%.

Ian
Thanks Ian.
Is the touch screen PC running the latest non beta Windows 11?
Windows 10 but fully updated, I tried win 11 and had some big issues (couldn’t get my PCs to see each other on the network and stuttering on the MSFS PC), so win 11 doesn’t work for me at the moment.
If you run other non Navigraph apps on the touchscreen PC, do you get similar behaviour?
All other apps, including simbrief, work perfectly and have done so since I started this setup in 2010.
Try this:
Right-click desktop → Display Settings
Check Scale
Temporarily set it to 100%
Restart Navigraph Charts and test touch again.
If that fixes it, you can try 125% instead of 150–200%.
I am currently on 100%, I tried 125% which was the only other option shown but no change.
More info on my setup as this might help:
Dispatch PC (desktop pc, non-touch monitor native res 1280x720) for flight planning
In the cockpit:
2x touchscreen monitors native resolution 1024x600
All 3 monitors are cloned/duplicated using Nvidia Control Panel (GPU RTX 3080 ti) with resolution of 1024x768
The touchscreen monitors point perfectly/accurately, I have checked this.
As mentioned, this has been working since 2010, only went wrong after introduction of scratchpads

We shall investigate.

Ian
Many thanks Ian, that will be a huge help.
If tapping a button opens a chart instead, that means the tap is being interpreted as a click on the chart area behind the UI. In other words, the touch coordinates are slightly offset. This is a classic Windows 10 touchscreen calibration / DPI scaling issue.
Try these fixes in order:
Then restart Navigraph Charts.
If the touchscreen is not the main display, Windows can mis-map touch input.
Even if it’s correct, resetting it can fix offsets.
Cheers
Ian
Hi Ian, I will do all the steps in your last post one by one, but I don’t think it is a case of calibration of my touchscreen, not least it has been working since 2010! I have checked it already and it is pinpointing very accurately, but I will do the steps.
Very important - different from what you said in the quote above, it is not the case that I try to press the trash can and it opens the chart instead. No, it is opening the chart as a map overlay, as if the trash can is not trash but the following symbol:
You can see this happening in the videos I sent, have a look again at this one, it is always opening the chart as an overlay:
I’ll do the steps and report back
Hi, I have done the following steps. (As an aside I don’t use Tablet mode, I never have, it is off, and Navigraph Charts is a Desktop app anyway).
1/ Updated the graphics driver, but no resolution.
2/ I did each of steps 1-3 in your last post and after each step I opened Navigraph Charts and tested, but the same issue occurs.
Very important, as per my last post, what is happening is the Trash can is being seen as the overlay button, here is another video I just recorded after the above tests which shows it clearly. This only happens with Touch, not with a mouse click, the latter works:
As mentioned, this only went wrong after introduction of scratchpads, it has been working since 2010

Hi Ian, just a thought, is there a way of going back to the version without scratchpads and testing that? If that works, would that help pinpoint the issue?
Hi Charles,
The development team are looking into it.
Cheers
Ian
Many thanks, standing by
Hi Ian, just checking in to confirm this is still on the list, I tested after the latest release today, but still the same issue, i.e. the trash can symbol behaves like the overlay symbol, and opens the chart as an overlay, doesn’t delete the chart when using touchscreen
Regards
Charles
