Bug? VS doesn't draw waveform for some imported WAVs

[TimArends]

Occasional bug in VinylStudio: When importing a WAV file from Audacity, VinylStudio doesn't seem to like the file and refuses to draw the waveform for it, or at some magnifications, it will not show the waveform but others, such as the very highest magnification, it will. Happens in both the split tracks window and cleanup audio window, except that in the split tracks window i can't magnify high enough to show the waveform. I have to try re-saving the file in Audacity and re-importing.  Happens about 10% - 20% of the time.

My System:
iMac 2.8 GHz Intel Core 2 Duo
Mac OS X 10.5.8
4 GB 667 MHz DDR2 SDRAM
VinylStudio v7.1.4. Mac
