Once in awhile, when I start Vegas, I get this error message:
"There is no disk in the drive. Please insert a disk into drive F:"
The F: is my DVD ROM drive. I never read any files from that drive from within Vegas. I have been unable to correlate getting this message with anything that I did or did not do in the previous Vegas session. If I start a second instance of Vegas after getting this message, that instance also gives me this error message. I get the message about every fifth time I start Vegas.
This is strictly a cosmetic bug, but like many bugs, perhaps it reveals something more sinister (or maybe not ...)
