Drag and Drop - Redux - Cannot D&D *from* TLB to Desktop

I have just tested again.

For clarification. Of course button D&D works *within* TLB. And if your press CONTROL you can make copy of button *within* TLB

But user *cannot* drag button from TLB and drop onto another toolbar (such as Desktop toolbar) or onto Start menu

If user press CONTROL and hold it down then DRAG and DROP will work from TLB to another toolbar or start menu.

BUT. D&D will *not* work if user does *not* use Keyboard only mouse

This is not consistent with Windows QLB.
Windows QLB can D&D from toolbar to toolbar without CONTROL key
