>When I run my vfp5 app on NT4/SP4 and go to a certain process, I get the above message & good old Doc Watson. Under Win95, there has never been a problem like this. I guess I'll have to install vfp5 to debug, but has anyone ever encountered this problem?

I don't know if you are doing anything like this, but we used to have a lot of small processes that were actually written in small programs - when we would run them, we got Invalid Seek Offset's out the !@#. We decided to take the code and place it in methods of a small class, and never ran into the problems again.
