Has anybody else seen this error in citrix

It is a VFP6 exe under a 70-100 user citrix farm.

When the second users opens a table they share? the file
handle with the first users. If the first users closes
that table then the second user gets an 1104 error
when i/o to that table.

I tried this suggestion from MS with no luck.
