(First post to net - please forgive any oddities)
I have had a problem recently which is very similar to the one described 
in this thread.In short I am using the custom MDEF along with the 
TearOffMenus included with Think Pascal 3.0.1. and am further customizing 
the MDEF to support a sub-menu for one of its items.  In the custom MDEF's 
 ChooseItem routine I attempt to do this by calling PopUpMenuSelect. There 
is a brief flicker of the desired sub-menu then the dreaded error -108. At 
this point I tried the tactics outlined by Pete Resnick

But to no avail.  Any further insight by Pete or others is greatly 
appreciated.  Thanks in advance.   - GSM
