I have a non-modal dialog containing several CBitmapButton controls. In the message handlers for the buttons in the dialog I set the button state. First I iterate through all buttons and removes the pushed state by calling SetState(FALSE). Then I set the pressed button by calling SetState(TRUE). It works fine, until the keyboard is touched. When any key is pressed, the state is reset and all buttons are depressed, which I don't expect to happen. No function that programatically changes the state are called. Why does this happen, and how can I fix it?
