I have an Access program written in 2003. It runs on 8 machines and only one machine has windows 7. It is this machine that runs queries very, very slowly. The other machines running windows XP have no problems at all.
Have several machines with Windows 7 and Office 2003 installed. Some of them run rather heavy Access applications without any problem or slowdown. Is the memory large enough on the Window 7 machine (7 is quite greedy for memory) ? Any warnings or errors in the Applications log file ?
