While running Quark 5.0 under Windows XP I have no trouble working on files. When I go to add two pages to a document I get an error message " Insufficient disk space to perform this operation -- try saving your file first (15)". It can't be referring to any of my drives, they are all huge and the C: drive has 20GB vacant. There is no swap file in Quark that I can fine, so what is it referring to? I know EE is not Quark-intensive, so if anyone here could refer me to other sites, that would help as well. Is there a partial upgrade or bug fix for version 5.0?
