Mucias gratias.
.. A few remarks after testing and doing my things.
1. shouldn't hide the gce button (>AutoCAD 2017 has gce), i turned it this off ; (dcl-Control-SetVisible Osnaps/Main/btnGce nil)
2. i cannot figure out how to set osmode = 0 seems some kind of bug that this will automaticly turn it on/off instead of resetten it all (to red buttons)
3. strange thing that the toolbar is shortening everytime i active it..(?) Why is this..? so i have set the 'enable resize button' : on
(the button aligenment need some fixing, i can do that

But what about the strange behaviour of the shortening at start up ??
.. still, this is amazing stuff..

Thanks!
Fun to do some testing / programming on a multi-platform basis..
