[AccessD] XP Quirk?

Hi

I am using A97 to export a file (using VBA code docmd.TransferText
etc.....acExportFixed) to C:\myfilename.
Hit a problem on a new XP machine with this installed - get error 'Database
or Object Read Only' when I try to export.
However if I export to C:\myfilename.txt it works - its as if XP requiries
an extension - anyone else come across this or can offer an explanation.

Cheers
