Ok, great.  That clears up some confusion.

Ok, that explains wtd.c.

Should be.  From the rest of your message it looks like the spec is to
send all GUI components back to the AS/400 as well.

You are right.  I'll have a look at wtd.c and see about adding in the
appropriate stuff to get the GUI components back on a RESTORE SCREEN.
I'll think that's all I need to get windows working correctly in enhanced
mode.  Scrollbars too :)
