Every time I "first launch" Acrobat 7 standard (i.e. when I haven't been using it for a while), as soon as I get into my document, start scrolling, whatever, it unexpectedly quits. I can then relaunch it and it seems to work fine.

I've done every 7.x update via auto update but nothing's changed. It's done this on my old G4 under 10.3.x, and on my new G5 under 10.4.x. I just chalk it up to crappy software, but perhaps there is actually a fix of some kind...
