John & Rod:

I found my problem! In my Expand method I was traversing the Child nodes incorrectly. I recompiled my code under VFP6 and it failed every single time, not just 20%. This made it much easier to pinpoint the problem. In VFP5, I was probably clobbering memory someplace else and was probably setting my self for a future GPF someplace down the road. It SEEMED like it was working, but it was not. Don't you just hate things working, but for the wrong reason? Oh, well, thanks again guys. Still have the other two questions...NODEFAULT and prevent collapse.

If I don't let it do that, it never fails to release. But I need to show lower levels that have other nodes. I don't actually populate the lower nodes until its parent is expanded.
