                 version to NullStr and all others to NULL.
   19 Jul 08 GKY Replace save_dir2(dir) with pFM2SaveDirectory; use pTmpDir for temp files
+  03 Aug 08 GKY Reworked FillInRecSizes to use pci->pszDisplayName for display names and
+                created a more consitent string for passing to DRAWITEM. Finally (I hope) fixed
+                the strlen trap.
