Hi Dan,

>PMFJI But I thought the ISEXCLUSIVE was only detecting if you had the file opened exclusively on the current machine.

Here's his code:

set exclusive on
USE xtable exclusive

isa = isexclusive("xtable",1)

so he's trying to see if he has the file exclusive on his machine. I'm, not sure whats happening. What if you specify an Alias and test that? Maybe the alias is already in use?
