Hi,
I have checked on the following page and found Windows 7 is not in the Supported Operating Systems. I suspect this may be related to compatibility.
Microsoft Visual FoxPro 9.0 Service Pack 2.0
Regarding this, please also run the application with Compatibility Mode and see if it works.
If the issue persists, it is recommended that you go to our Visual FoxPro Forum for help.
Thanks.
