>>I have an app that was working OK. I changed a page on a form and then started getting sporatic 'invalid control source' errors when the form closes in the application. Stepped through the entire close process and the message will come up when I am just sitting with the debugger open. After messing with it, it finally consistently comes up with the error. I decided to just revert to the version that worked before. I restored just the form class and found the same trouble. I then restored the entire application and still have the same trouble!

Thanks for your replies. I have already checked the data.
What I found was that somehow a copy of the class library my form class was in got into a directory that is used for common libraries. My take on it is that at some point VFP was looking at the correct one and getting class names and locations and then at another point was trying to find a new class or two in the old classlib. I don't know. I do know I am much happier now that I have removed the old lib!
