Is there a way to determine which window is receiving keyboard events?  I 
have an application that I have written and at times my keyboard shortcuts 
don't work even though the application has focus.  I have an ActiveX control 
on the form which I think is causing the problem, but I don't have a way to 
verify this.

Keyboard messages are usually posted, not sent.  When a message is removed
from the message queue, the MSG structure contains a HWND specifying the
window that the message was posted to.  If the HWND is NULL, then the
message was posted to the thread itself instead of a specific window that is
owned by the thread.

You can use the TApplication::OnMessage event to intercept messages that are
received in the message queue.
