"Error: File table full" in VB app

[Dan Kegel]

The next buglet in the property management VB app from http://www.yardi.com
is right after I pick the datafile to open, it pops up
with a dialog box titled "Database Exception",
contents "Error: File table full.  Op: Open.  File: BANK.DAT [86:0:21]"

Now, what file table might that be?
I tried editing c:\config.sys, and adding FILES=128, but
that didn't help :-)

I'm attaching the output of
~/wine/wine --debugmsg +file,+dialog,+int21 --dll compobj,storage,ole2,ole32=n  Y.EXE > y.log 2>&1
tar -cjvf y.tar.bz2 y.log

Suggestions welcome.  I'm more than happy to raise that
file table size, if only I knew which one it was...
