I have been using Audacity for music recording for many years now. It is a great tool and I appreciate your work on it.
However, there is a new and nasty bug for few months:
The keyboard shortcut Shift-Ctrl-E does not work anymore.
The UI gets in a very strange state in which it cannot be operated properly anymore.
After pressing Shift-Ctrl-E again the UI becomes operational again.
Expected behaviour: Pressing Shift-Ctrl-E opens the file dialogue to export the tracks, e.g. as MP3 file.
This seems to be a pure UI issue.
My Operating system is SuSE openLEAP 15.2. My desktop is KDE plasma5.
