After I first updated to 2.0.3 on my (original) MacBook (using the Boot Camp partition for VMware Fusion) Windows XP Pro wouldn't restart - using shortcut, using Start menu, or using DTaskManager. Neither would it shut down using any of those methods. VMware Fusion wouldn't quit either... To make a long story short, (I use MacFUSE and NTFS-3G) once I got it running again it didn't have any problems. I thought 'somebody' might appreciate hearing that it's a temporary glitch and not to give up.
On a separate note I can report that I discovered (in 2.0.2) that Windows runs faster on 1 processor and only 512 MB RAM. [This machine has 2G RAM total, of which I had allocated 1G to Windows.] This still holds true for 2.0.3.
