Has anyone else encountered this behaviour with the Fuzzy Lookup Add in, and if so is the reason known and has anyone got any work arounds other than the one I'm using.

From time to time I've used the Fuzzy lookup and I don't remember this particular behaviour before.

I have a workbook that contains a couple of tables that need to be compared with the lookup and all works well exactly as I'd expect.

However when I open another workbook and create another fuzzy lookup with another pair of tables and a join nothing happens when I press the Go button. It makes no difference whether the first workbook is closed or not.

I've tried the obvious stuff like closing the Excel App and restarting and re-booting the whole laptop.
I've also uninstalled the Fuzzy lookup and re-installed from scratch still to no avail.

Only the first workbook fuzzy lookup will work and I can only compare other tables by adding them to the first workbook and changing the table names in the lookup.

Usual thanks in advance
