Trying to export as tab delimited fails on a two field database with 6 records fails consistently; exporting as CSV works fine with the same database.
Oops. When I used CSV for the export, it appeared to work, but the .txt file never showed up in the folder. Perhaps the file is corrupted, as any attempt to print crashes PanX. CSV export attempt shows:
Is there any chance that there is a permission issue with the folder you are attempting to export the data into? Perhaps try exporting to a different folder?
