Is there any way to have this clip protected, but still let the thumbs update during a scroll during my mouse drag?

I seem to remember that in FB3/4, when a thumb was moved with the 'scroll button' statement, the scroll bar (via special runtime code) would add itself to the clip region, redraw, then restore the previous clip.

You could get a similar effect like this: 
fn ClipScrolls( wndID, _false )
scroll button .... // move thumb
fn ClipScrolls( wndID, _true )
