For example, when expanding the Alternate Airports section, the Find button corresponding to the Enroute Alternate is one of the “worst offenders”, in that I sometimes need to click it more than twice before something happens.
This has been happening as far as I can remember, on multiple computers (albeit all macOS-based, I guess), across multiple browsers (specifically, Safari and Chrome), using both the trackpad and more than one external mouse. The click seems to always be registered (the Find button animates to show a “press”) but often nothing happens.
And it’s specific buttons, too, most of the buttons work 100% of the time, but finding takeoff and enroute alternates is indeed somewhat/quite unreliable for some reason. I seem to possibly recall one or two other buttons having issues but cannot remember which ones specifically off the top of my head.
