I see one other user having trouble with audacity (importing mp4), but my issues are more comprehensive - if somewhat vague.
Audacity tends to lock/freeze and even make the entire system unresponsive. It is typical in my experience to stress the software with navigational clicks, track modifications (such as Effects --> Amplify), selection of a portion of a track for export, and/or repeated clicks of the arrow to advance a track in the window. Sometimes - perhaps most times - the software will thaw/unlock after a period of waiting . . . but other times, such as yesterday as I selected the entire 55 minute track, started the process of amplification, got up and walked away while that process was taking place, I returned to a completely unresponsive system. Fortunately, Audacity recovers tracks upon restart, so I didn't lose the music.
There are a three bug reports on Audacity, two of which are in Turkish, so I cannot tell whether this issue/these issues have been reported. I don't want to file a duplicate report, so am requesting some feedback here on the issues and the bug report(s).
