How do I include in a dialogbox, an editable text field that handles
more than 255 characters (say, a field that can scroll through several
PAGES of text)?  If I treat it as a useritem, how do I handle TABS
so that the cursor flows from item 1 to 2 to 3 in the outline below?

According to IM vol1, p422, GetIText and SetIText can handle only 
strings up to 255 characters.  I'm sure this problem has already 
been solved many times.  Please mail me any suggestions.
