yes, I posted the same distinctive feature yesterday in my mail "HTML-Frames, 
one-way commandLinks and forced frame reloads". This is imho not a 
tree-problem, it is a problem that  emanates from the combination of 
html-frames and commandLinks but I have defnetly no idea what the source of 
this misbehavior is.

Lets hope that somebody in this list can help us, because just like you guys 
it drives me also crazy...
