[Mad Hatter]

I use to have crashes frequently in the past as well. I thought it was due to...

MS Opticalmouse driver at one point
OmniWeb plist (very possible)
Bookmarks file - from using Bookit to synchronize

I would use one of the 4 buttons on mouse assigned to command + W, and another button was assigned to Command + `

And because the plist does get updated a lot, and holds all the site preferences, that is a very very critical file. Needs to be backed up a lot, use Applejack and a plist checker, maybe Property List Editor can verify?

it got so bad, and OmniWeb would sometimes show the "Application Not Responding" (javascript on some shopping carts especially) that I removed the OmniGroupCrashCatcher.app just in case it was a 'false catch.'
