Luckily I rebooted and everything was ok. Yep, rebooting is still the best way to fix most Windows problems. Things haven't changed much in the last fifteen years.
Actually I still have other problems with Vista. I still get problems caused by Windows Firewall. Vista was so unstable on my MacBook under Parallels that I replaced it with XP. In December, my Vista install was completely corrupted. After several minutes of use, its network and memory consumption would go ballistic making the system unusable. I thought at first it was a virus or malware of some sort, but I never found any evidence of either. I wound up re-installing Vista to fix the problem.
Now Vista SP1 is out. I don't know if I should be hopeful that it will be a remedy for all of my pains ... or if it will just be fuel for the fire and cause me to "upgrade" Vista to XP.
