I am currently running Windows 98, the first version. Before I started using Access I very rarely "locked up." But now, after installing and using Access, I get very frequent crashes of the Access program, not my whole computer just Access. It says it is very sorry but it is shutting down and do I want to send an error message to Microsoft. Then it shuts Access down and I have to reopen the program. It also creates a backup file everytime it does this. Is this happening because I am using Windows 98? Do you think it would help if I upgraded to Windows XP. Thanks.
