Perhaps my problem(today's "Logic/Mouse Issues" post) may be "root-ish" in nature. Aside from the pull-down menus sporadically working right and not being able to adjust any plug-in windows, the other issues are: mouse "sticks", where if I click in the Matrix Window to move a MIDI event the event will move again after mouse release and I have to click on the event again to "release" the first click; I have a long tone at the end of a cue and when I go to bar 1-1-1-1 (Arrange Window) the tone continues even though I'm at the top of the score and there's no data on this particular track until close to cue end, the tone did not stop at cue end even though there was no data in the Arrange/Matrix window at all; I've noticed the last few days' saved work is not dated correctly even though the Apple date/time display is correct; since my last post the Auto s'ware name pop-up on the Dock wasn't working, but was corrected on restart, and finally, drag/drop in Finder monentarily freezes before working. I've only noticed these issues in the last few days as I've been scoring since late Sept w/no issues at all until recently. I haven't been crashing Logic Pro w/too much CPU demand and have been running Disk Utility regularly.
