Q: Responding to Double Click versus Single Click

Using TPW 1.5

I want my program to respond to the user's having clicked on a certain area of the screen.
 I want the program to repond differently if the user double clicks on the same area of the
What I have done is to override the wmLButtonDown and wmLButtonDblClk procedures.  Unfortunately,
I find that double clicking mouse send a wm_LButtonDown message first, and then sends the wm_LButtonDblClk.
 I want some way for the program to ignore the wm_LButtonDown message (or at least immediately
exit from wmLButtonDown procedure) if there is a wm_LButtonDblClk message in the queue.

I thought I might be able to use PeekMessage with a range of wm_LButtonDblClk to wm_LButtonDblClk,
but this doesn't seem to work.  I'm guessing that this is due to the wm_LButtonDown message
having already been processed by the time the wm_LButtonDblClk message enters the queue.

Am I missing something obvious?  Am I approaching the problem the wrong way?
(I can't subtitute left double click with right click since I am going to use right click and
right double click for a different purpose.)

Thanks in advance for any help.
Please post response, rather than e-mailing.
