OS X 10.5.7 Lockup Update

As I’ve previously written about here, here and here I’ve had problem with my iMac since installing OS X 10.5.7. I’m pretty much at the point of installing everything from scratch one last time and extensively test after each and every update.

Until today when I realized the easiest way for me to reproduce the problem was to minimize iPhoto or iTunes to the dock. (These are the only two apps left on my iMac that I’m using.)  So just for the hell of it I decided to switch the minimizing from the genie effect to scale effect. (In System Preferences –> Dock –> Minimize Using)

Other changes have seemed to resolve the problem only to have it return within a day so I’m not calling it a confirmed solution yet. But I’ve been unable to reproduce the problem with scale effect set, despite what must be over a hundred attempts by now, yet when I change it back to genie effect the problem occurs within three attempts.

I’m cautiously optimistic but wouldn’t be shocked if Mr. Murphy is just teasing me. I’m trying to not think about how this can make any sense.
