It really has nothing to do with the number of files.  It's the number 
of characters contained in all of those file names that's the problem.

I'm working on a dynamic solution based on this info from the SDK:
"The buffer pointed to by the lpstrFile member of the OPENFILENAME 
structure is too small for the file name specified by the user. The 
first two bytes of the lpstrFile buffer contain an integer value 
specifying the size, in TCHARs, required to receive the full name."

However, this only seems to be true to a certain extent on my XP system 
so I need to to more testing at home.  One *possible* reason for this is 
that the OPENFILENAME structure has 3 extra members in XP:

#if (_WIN32_WINNT >= 0x0500)
  void *        pvReserved;
  DWORD         dwReserved;
  DWORD         FlagsEx;
#endif // (_WIN32_WINNT >= 0x0500)

It would be easy to modify the lib (this structure in particular) using 
GetVersionEx to take advantage of new/extra features.  The question is, 
if I can make this work, will Derek add it or will I be wasting my time?
