I used to suffer BugSplats when I used SU5 on a pc years ago. Since switching to Mac 5 years ago never had a problem. However, I've had two bugsplats this week whilst working on simple floor plans. Very odd!
I can report that having the Components Window pane closed while fiddling with the Outliner dramatically reduces the likelihood of crashes. I had been getting crashes in relatively small models too, so I think there is a problem with the code somewhere.
I use a Mac also.
