Have been running Visio 4 (I still have some clients using this version!!) under XP in Win98 compatibility mode, successfully for some weeks. Today it refuses to print and says "Visio Internal Error #2107, Action: 1010 Print". Have tried reinstalling but no joy. Visio not available for uninstall from Control Panel - why? Any ideas about fixing print error problem? Printer is HP Deskjet 895Cxi.
