Can someone explain to me how VFP 6.0 running on NT 4.0 service pack six deleted all method code in a class I have been working on all day!! All assign method code as well.

I was running the application, extied the application, opened the class to add one line of code to an empty method, saved the class and run the application again. The class had none of the functionality it had previously. I exited the application and opened the class to find all method code gone except the one line of code I had just added.

What the f..., This is a serious problem. Has anyone ran into this before?

Thanks,
Bill
