My app launches a dialog from right clicking a node in a tree control
(similar to Win explorer i.e. 2 views) The dialog box is displayed
however it will not accept mouse clicks in the dialog, so the dialog is
unusable.

This condition can be cleared (made modal) 3 ways:
   1. By right clicking anywhere OUTSIDE the dialog
   2. By left clicking in the tree control
   3. By task swapping away and back to my app

I launch 3 dialogs from the same menu popup, 2 fail like this the other
is modal acting.  The only difference is the working one is in a
property sheet.

Thanks in advance for any advice!
