Why do I find the weird ones? 2 networked systems, both running XP (1 on SPI, the other SPII), Both running Quark Express v8. Files saved and closed on the local machine in a shared folder are not available to the other machine. The error message is 'file not available (file open)' No offer or a read only version. Turning it all off sometimes clears the error. It only happens with this app - all other apps are fine. Changing to another spreadsheet is not an option, Any ideas anyone?
