Dear support, I'm quite happy with this outstanding product so far. It is really great, and I would like to help to improve it further. Of course there are little problems in this early state. One of them seems to be a rare case that I have hit using two virtual disk images. I have two virtual drives C: and D: Each of them is a single partition. This just happend after trying lots of configurations. Drive D: should have been simply a network share, but this was not possible due to a bug in the subversion windows core which makes it impossible to check out to a network drive. So my C: and D: partitions reside on different mounted virtual dynamic drives. After moving many files to the native OSX fs, I tried to save space and compress the drives. The C: drive shrunk nicely, while the D: drive stayed unchanged. What I used was the automatic compression feature. I tried several things, also using disk defragmentation from PerfectDisk(TM), but this did not change. So I tried to compress the D: drive manually and it just worked great. I guess there is a missing case if more than one virtual drive is attached. Cheers - Christian Tismer
