Aircraft tag vanishes too quickly

Hello, thanks for upgrading Charts app, which I found very useful.
I found a problem with traffic displaying. When I hoover the mouse over one aircraft to retrieve its basic flight data, the label reporting the info appears but vanishes too quickly to be read. I checked that this is not due to me moving the mouse far from the aircraft icon, and that this happens for both IVAO and VATSIM traffic.
Every worked normally before the update, so I reckon it will be not difficoult to restore the previous behaviour.
I have charts on win10 (simlimk correctly linked to XPlane, if this matters). Thanks for considering this and for the great tool you are developing.

P.S.: clicking on the aircraft shows the information in a separate window as usual.
