I found a script that can highlight controls. That was done by Larry and was called outlinecontrol. It's pretty cool but does not work on windows like the explorer, the autoit-helpfile and so on. Now I found the time to toy around with other scripts that do that, and I think it works just as needed. But how do I remove the old stuff? I thought resetbox() should do it, but I was wrong. What did I miss?

Yes, this works: Just Replace the ResetBox Func with code borrowed from matrix200. :whistle:
