Steps to reproduce:
1. Run the app, capture audio from cassette tape.
2. Hit stop and go to the "Preview and Edit Recording" screen.
3. At this point, everything works - I can preview tracks or play any portion of the recording.
4. PC goes to sleep
5. PC resumes from sleep
6. The track preview and play audio buttons no longer work. Pressing either one does not play any audio and the Time counter does not change.
I did do a search in the forums for "sleep" but got no hits.
