I just applied the IPatchFP patch to some older FoxPro 2.5b for Windows programs in order to get past the divide by zero error on XP Pro. I also patched the actual FoxPro software itself. FoxPro runs under XP now and if I open the project file for a program and run it as an app it works fine, the problem is when I try and run the EXE file or open it, it bombs out. I get no error message, nothing, just an hour glass and FoxPro opens for a second then closes out with no error messages, any help MUCH appreciated as we have like 20 programs that have to work under XP until we can rewrite them all with Visual FoxPro, thanks.
