Just a heads up to anyone who trys it. Adobe Photoshop Elements 2.0 wouldn't install on my new iBook while logged in as my default (Administrator) account. It kept giving me an error (sorry I don't remember it). Only after logging in as root was I able to complete the install. I'm not certain if this is due to having installed 10.2.3 or what, I was about to back-install if logging in as root didn't work. Remember that you have to do some NetInfo tweaking to enable "Login as Root."
[Editor's note: I've heard sporadic reports of this problem with Adobe apps in general, and I'm pretty sure they pre-date 10.2.3. Does anyone have the definitive cause and/or solution to this potential problem? I say 'potential' as I've installed Elements a couple of times now and never had any trouble with it, but I haven't reinstalled it since upgrading to 10.2.3]
