>When the Hot Tracking button in focus it has 3D border.. no ways to the make borders disapear. There exist VisualEffect runtime property, but its not help you disapear borders. I did button, place this button out of form visible area.. and in Hot Tracking button MouseLeave write code thisform.outofscreenbtn.setfocus().

You may take a look at a reply I just did in this thread. Basically, I see a full button with a white background even if my button as Themes=.F. and SpecialEffect=Hot Tracking even at design time and at run time.
