Well, I've had 10.3.3 running for a few days now, and I'm starting to get a feel for what's fixed and what isn't. It's obvious that Windows networking has had a pretty major overhaul, and is a big improvement on the network at my job. But I was more interested in some of the annoying little things on my G5 2x2 at home. Good: -"Slow" startup fixed; now at the login screen in something like 20 seconds. Nice. -UPS detector seems to see my APC XS1000 and report battery status. Haven't checked whether it'll actually shut down the computer yet, but I expect so. -Feels a little more responsive all around. -My extremely flaky Belkin USB2.0 hub (it has a tendency to loose connected devices after the computer is restarted or put to sleep, requiring the hub to be power cycled to see them again) seems to be somewhat less prone to forgetting stuff is connected. Stupid Belkin hub--my old $20 RadioShack el-generic hub never had these issues. Bad: -There seems to be a conflict with APC's Powerchute auto-shutdown software; while I had it installed, the computer crashed (fans all on full, no other response) twice when trying to sleep in as many days. Since uninstalling it, no problems in three days, so that seems to have been the issue. Not surprising, I suppose. -The glitchy icon issue still isn't fixed; I now have all url links showing as Quicktime streams, and all quicktime streams showing as the address book, for example. Might actually be worse than before the upgrade, but considering how common and annoying this is, seems like there would've been a fix in there. -My netstat process still freaks out after about two days of uptime for no apparent reason. This one has existed since I upgraded the G5 to 10.3, and I've seen reports from about three other people, all with 2X2 G5s with upgrade installs of 10.2-->10.3, and all with over 2GB of RAM. Can't say I'm surprised this didn't get fixed, but hope springs eternal. And yes, I'm aware that my last problem can probably be cleared up by a reinstall, but with the number of custom Perl modules I use, I'm loathe to do that unless desperate. Oh well. At least nothing new is broken! How about other people? After using 10.3.3 for a week, have you noticed other things that do or don't work?
