And this doesn't just happen occassionally - it happens all the time! It really is a pain in the ass. If you do a "modi class bla method blech", and it's still in memory, it's so easy not to notice, and you can screw everything up. This is a huge bug. It seems to happen more when I'm using multiple tiers of objects - i.e. I'll visually design a class, then visually design another class and plop the first class on it, then visually design another class and plop that last class on it. It seems that if I use addobj() instead of doing it visually, it happens a lot less.

I can sympathize with Bill - I lost a day's work on Friday.
