I've had only three problems since upgrading to Snow Leopard. Let's see how 10.6.2 dealt with those problems:
BEFORE: When opening Firefox, it stays in the background, unfocused.
AFTER: Firefox STILL stays in the background, unfocused.
Okay, this is now an issue about half the time....not a HUGE deal, but it would be nice if it did focus properly...
BEFORE: Internet not accessible via wifi unless I futz with the settings each time I reboot.
AFTER: Internet still not accessible via wifi unless I futz with the settings each time I reboot. (And yes, I've tried all the "solutions" -- trying a new "Location," manually adding the DNS numbers, deleting the files from the Library folder, etc. -- nothing worked.)
Okay, this issue is now solved...I tried rebooting my router, same issue. Now...bit of a story...where I live the phone company just added an overlay, so we now have to dial 11 digits (1+area code+phone number) even for local calls...and for some reason we just can't get our TiVo to dial out with the new configuration, no matter what settings we tried...so we switch to wifi on the TiVo...THEN suddenly my MacBook has been flawless with wifi!
BEFORE: Can't drag and drop more than one message at a time in Mail, except maybe one out of 30 attempts.
AFTER: Still can no longer drag and drop more than one message at a time in Mail, except maybe one out of 30 attempts.
I did a search on the Apple.com discussions to see if anything further was discovered...apparently, 1) the techs at Apple can't replicate the problem, 2) none of their troubleshooting (reformatting, reinstalling, reimporting, starting fresh, etc.) works, and 3) one workaround is to highlight the messages you want to move, let go of the mouse button, THEN drag the messages. I tried that, and it works....but you can't highlight a bunch and drag'n'drop in one move like before. Doing the two-step is a very, very minor inconvenience for me, so I'm glad I checked back.
