Audacity is not responding Process ID: 2344

[Kenneth]

When editing a WAVe file, Audacity stops responding. Sometimes I can close the application, at other times I have to reboot. It seems more noticeable when I perform several sequences quickly, like jumping around to different time positions and playing from that position.

Also running at the same time:
Dolphin
Oracle Virtualbox Manager (XP launched)
Sometimes Google Chrome

Still happens every time with 2.0.5-1

Application "audacity" is not responding
You tried to close window "MyAudioFile" from application "audacity" (Process ID: 2895) but the application is not responding.
Do you want to terminate this application?
