While my desktop app (Win, Mac, Linux) is getting bigger I found some weird behaviours:
Windows: Change event on Combobox does not fire when text was manually entered and Combobox was left. Choosing an entry from the predefined list is still working (trigger fires). When leaving the changed field with TAB I hear a short “blocking” sound, no sound when pressing RETURN key. I have several windows and no matter where I create a Combobox I have everywhere this effect.
Mac: cmd+C (copy) and cmd+V (paste) not working in any text related field, both with short blocking sound.

Combobox: I am already using the CHANGE even that should fire on leaving the combobox, I’m not the TEXTCHANGED event. It works on the Mac side, not on the Windows side.
Copy/paste: I have a menu with short keys in the app but I made sure the cmd+C and cmd+V are not occupied that way. Aaah, you mean I must add those commands ALSO also as menu items! Good point, will try out, thanks!

That’s a good question. For the time being I’m not able to reproduce in a much more simpler app. This will cost me a lot of time to fiddle out where/in what constellation this problem occurs. When time is given I will give it a try, thank you!
If you can’t reproduce it easily on a simple project then all I can suggest it see what events you have on the ComboBox and breakpoint them all, step through until you hear the Beep so you can find out what is causing it/when its happening as this isn’t standard windows behaviour and is probably a result of your code. Also check any Super’s for forgotten code. Good luck
The lack of Change event firing if you happen to type the exact word from the drop down list I’d consider a bug as the next time you visit the control the new entry is selected. I’ve just had a quick play around with the control and I’ve spotted a few problems with it that I’ll make feedback tickets for.
