I have a custom dBase IV 2.0 multi-user app (.prg files) installed on a Windows ME machine. It runs fine on the ME machine.
The same .prg files also run over the LAN on other PCs, accessing the same .dbf tables. This app worked well for years under DOS, Win 3.1, and now ME. But with XP, I find that the app doesn't run reliably for long. It will run, but after some time (usually when Enter or Page Down button is hit), the app seems to hang for a long time (5-10 minutes) before coming back.
Over the years, I have made the following changes to keep it running under newer, faster machines with bigger drives.
1. IDXFIX to avoid "File already exists" error
2. Putting the database files in their own partition (under 500Mb) to avoid "Not enough disk space" error
At first I was using cmd.exe, but yesterday I changed it to use command.com. Still, the same problem exists.
Any help or pointers are appreciated. Could this be due to undefined printers and timeouts?
