Funky. VS 2005 decided it didn’t want to let me use the Find and Replace dialog any more. Hitting Ctrl-H knocked the IDE into the background (pale title bar), but no dialog would come up. Losing the find and replace functionality sucks, to say the least. I restarted VS, no help. Now this is getting really irritating.
I finally fixed the issue by resetting VS’s settings via Tools -> Import and Export Settings -> Reset All Settings. Whew.
