Hi,
I don't know how it is called in English, but I'm talking about the effect that a form normally docks on the screen border when moving to it. When moving to the left or to the right, a window will cover the left part of the screen or the right part, when moving to the top screen border, a window will be maximized. This works with Alpha Controls (9 beta) – however the marking on the screen will not be shown when still moving. BUT: When a window is maximized, it can not be dragged back in its normal state. When setting TsSkinManager.Active=False, all works as expected. I tried it also with TsSkinManager.ExtendedBorders=False, but without no difference.
Please note, I'm using Alpha Controls Beta 9, but I think I had the same situation with version 8.x.
Best regards
Friedemann
