I have a database that I previously ran successfully on a Windows XP system. I recently received a new PC with Windows 7 Enterprise (32 bit) that is having issues with running queries from the same datatbase. I am still running the same version of Access (2003) on the new laptop but the queries seem to stall out and Access becomes non-responsive. Can switching from one operating system to another cause this issue? I am really just starting to use Access, so I am a novice at troubleshooting and thought that I would ask this question before digging deeper.
