>>>>>My application was working beautifully in VFP6 and now I'm having a problem in VFP7. I have a form class that accepts up to 7 parameters. When I call it with 4 parameters it works, but when I add a fifth, it crashes. It doesn't matter whether the fifth is blank or not, and it doesn't get beyond the parameter statement. Any ideas?

While I have no idea why this was a problem, the problem was that I couldn't pass more than 4 parameters. So I collected the parameters into an object and passed the object and now all is well. This has to be the craziest bug I've encountered. Thanks to all who tried to help!
