Tiger Bugs
I've been keeping track of a few bits of odd behavior in Tiger, and following up on Laurie's post about Quicktime bugs, I thought I'd turn my observations loose and see what the rest of you have experienced. I've noticed that Safari RSS sometimes lists the time for posts an hour ahead of the actual post time. When this happened earlier, this TUAW post at 1:25 was time-stamped as 2:25 in Safari RSS (when I looked at the feed at 1:45).
I also had the Finder just crash on me when I closed a Spotlight search window. After it relaunched, MenuCalendarClock was on the other side of what should have been the corner of the screen. Quiting MenuCalendarClock didn't help, so I had to Force the Finder to relaunch (Command + Option + Esc). Admittedly, this could be a MenuCalendarClock bug rather than a Tiger bug, but I don't think so, as the Finder crashed when I closed a Spotlight search window and no where near MenuCalendarClock and Spotlight's menu icon.
These are just two little quirks and possible bugs that I've noticed. What Tiger bugs have you spotted, TUAW readers?
