Parallels 5, I have a disk image that could be 12 gigs smaller if compressed. No snapshots or undos. Clicking the Compress button in the disk settings does nothing. I get a progress bar for about 5 seconds and left back at the disk settings area, no error messages are given. My free disk space on the mac side is low, only 4 gigs free. here are some errors from the os x console: 11/30/09 10:39:29 PM [0x0-0x72072].com.parallels.desktop.console[2465] QImage::scaled: Image is

Another data point to add... the VM that won't compress was created with parallels version 3, upgraded to version 4, and then upgraded again to version 5. I tried another VM that was created with version 5 and it compressed with no issues using the same command sequence outline above on the same host.
I just upgraded to Parallel's 5 (started at 3). Cannot compress. The message I get is that the disk is corrupt, or there are snapshots (there are none). Substantial disk resources can be saved if this is resolved, please advise.
