There seem to be two different crashes to investigate: 
1. When starting calculate from the IDE, and, once you get that one fixed:
2. When closing calculate.

I'm using Win 98 and Derek's latest 55.5 version of Win32Lib.

In  function fDoTVN_GETDISPINFO() around line 20,238 I get an error about 
trying to access the 0'th element of a sequence. Here's my patch, which 
may not be the right thing to do, but it gets us past the error:

 -- This is called before we get the handle, so if
  -- we haven't filled it in yet, we'll just grab
  -- the first one.
   if not lItem
   then
      -- lItem = find(0, tvitem_handle )
      lItem = 1 -- IGM 01/12/2001
   end if

Now, the program will run from the IDE, but will crash with a Windows 
Meaningless Error* when closed. This can be fixed by changing the owner 
of the HelpWindow from 0 to CalcWindow. Now it will run ok from the IDE or 
directly.

Can anyone provide a "proper" fix for Win32Lib?
