I haven't had any serious problems with SP2 on my M6809 (still running Home Edition till I can get Pro cheap on campus), but there are several little annoyances that I can't figure out, mostly stuff just not loading. For example, when I click the speaker icon in the system tray, the volume slider no longer comes up, nor does the panel when I double-click. If I try to click anything in Administrative Tools, nothing will open - nor will they if I run it command-line style (e.g. services.msc). Shortcut keys still work. I'm sure there are more glitches, I just haven't run into them.
Anyone else experience this, or have any thoughts? I'm fairly certain it's related to SP2 somehow - the problems vanished when I uninstalled, and came back when I reinstalled.
