I have a 5.1 MB .WAV file that I'm opening in AA Studio. When I open it, defaulting to 320x240x965fr, I get the following error: FLIPPER An error has occurred in your application. If you choose Ignore, you should save your work in a new file. If you choose Close, your application will terminate. If I close, I get the following GPF: FLIPPER caused a General Protection Fault in module STEALTHT.DRV at 0001:9F7E. This is obviously a problem with my Diamond Stealth driver. If I click Ignore 3 times, the program opens and functions until I attempt a render to several hundred frames whereupon I get the same aforementioned GPF. If, however, I click Ignore 3 times and then save the .WAV as .AVI, quit and then reopen the .AVI, I can continue without the FLIPPER errors. I looked for FLIPPER in both the manual's index and the on-line help, but did not find it. Can anyone impart some information to me about the cause of this situation?
