I'm not sure if anyone can help me with my problem. Have done a new install of Win98 then loaded Works 2000 suite successfully. No problems, no errors on Pent 500, Gigabyte MB, 128mb RAM, 13gb HDD. Works Calendar developes problems with the following error popping up... "WKSCAL CAUSED AN INVALID PAGE FAULT IN MODULE MSJET40.DLL" If I disable Calendar I get other errors popping up. Have reloaded several times with same results occuring a day or several days after installation. I suspect Logitech Mouse drivers may be at fault but cannot pin it down. I found a patch for MSJet 4.0 but don't know what it does. I believe MSJET is related to searching database files but don't know how to fix the problem. Can anyone please help??
