I tested a solution adding buttonframes on METRO - buttons on action / click
because there is a missing visible effect. ( showing white button-frames like in Windows10 )
I would like to do this on mousecaption as well, but bGotfocus and bLostfocus doesn't work !
The solution takes care of using normal or large buttons.
It is working for me, but maybe there is still another solution possible.
I noticed changing the button-pos., there is a problem.
