Stefan,

>This was one of the tricks i could have lived with. But it does NOT work. It doesn't matter whether the shape is enabled or not, the treeview IS responding.

Ahh, Of course... The treeview is always on top and thereforre you can not put a shape above it unless...

I know you can make a top level form which is transparent and put it over the treeview. I know there was a previous thread about how to accomplish this. But this is kind a tricky. I don't know if you want to go this way..

Walter,
