A client has a screen with a list box (>400 records) that is generating an "Insufficient Memory" error on some machines (NOT all). I have read the previous messages here and tried the following:

- Added memlimit = 80,8192,32768 to CONFIG.FPW
- Applied PATCH_26.EXE.
- Added FILES=100 and BUFFERS=80 to CONFIG.SYS.

None of these worked.

Any suggestions? Why do some computers not have this problem?
