an error I get when I run 2 of my programs

[Wardlow]

If I run one instance of my program, I'm fine. However if I run (2) 50% of time there will be an error in 1 causing it to close down. I have a feeling that there isn't enough memory available which is causing the error. Is there something I can do where I still can run 2 instances of this, but not get this error?

Thanks

no one knows...

An easy way to find the reason is running one instance and then tracing another instance.
