I seem to be having a great deal of difficulty getting the dialog manager
to draw my userItem. It seems that when I attempt to return from the 
function in which the drawing occurs, that it is returning to some unknown
memory location (somewhere not in my program atleast) and crashing. I have
been writing this on a Mac IIci with Think C 4.0.

I call the routines to set up the function call as follows :

GetDItem(theDialog,itemNo,&itemType,&item,&box);
item = (Handle)DrawItem;
SetDItem(theDialog,itemNo,itemType,item,&box);

Then I use DrawDialog(theDialog) to draw it. The problem does not have anything
with what happens in my Draw function. Any insights into this problem would be greatly appreciated.
