Thank you, that is quite helpful. I already looked at this method in
the VB group disccusion were you were involved in December.

I do find it weird that your userform stays visible when doing a
resize of the window width (height alone is good) and on my PC the UF
window isn't visible after the width resize. When I use getwindowrect
it still delivers the coordinates of the UF window, though it isn't
visible. What does this mean?
