File extensions that are not recognised can cause server errors, a fix
should be available soon (or try some of the patches on

In normal CKAn behaviour an unrecognised file format triggers a save dialog box if clicked on, but for these files which are underlying txt format but varying (undefined) extension they cause an error.
