The problem occurs when clicking on something within a BS_GROUPBOX button.
co_IntTranslateMouseMessage sends the groupbox a WM_NCHITTEST, receives
HTTRANSPARENT, and posts the message to the actual control.

co_IntPeekMessage is called twice; once without RemoveMsg and once with. Each
time, it calls co_IntTranslateMouseMessage, so the control gets two messages
posted to it.

This weird way of redirecting mouse messages could also cause the opposite
problem in unconventional message loops, such as that of modal dialog boxes.
For example, run mstsc and click on a control - nothing happens at all.
