How do you limit the size of VirtualPC's disk? I'm using VPC7 w/ WinXP and the disk is currently dynamically sized. It seems to have grown about 30% over the last month. It's 2.33G now and I'd like to keep it at that size or smaller. I changed the disk setting to make it a fixed size, but I never saw an option to set the size. It just set the VPC disk fixed at 15G! ... so I set it back to dynamic and now I'm stuck at 2.33G, which still seems too large.
