I don't think I made myself understandable about that Autosize problem.

I'll post an exemple soon, but it doesn't react the way you explained it "should"

That seem to confirm I have a problem.

as for the TOp property, I know how to fix. I had a similar problem in past.
You'll have to Edit the file from external source (Ex.: Notepad++) as Vb won't allow this change to occurs because it is case insensitive, therefore he doesn't see the difference. Or, you can (in Vb) temporarely change the property to a different name (let's say "TopB") and then, remove the added caracter. it will then understand the change.
