I knew I was in trouble when...
...The client got a 'file does not exist' message when attempting to do a form that executed perfectly from my Development PC.

I have two pc's - laptop and desktop (where I develop the app) -connected to my network. I installed the exe on the network drive and executed it from my laptop. Sure enough I get the 'file does not exist' message when attempting to do the form.
I executed it from my desktop pc and no error.
I rename the application developement folder and launch the exe again.
Lo and Behold I get even worse errors:
The security is turned on and an error is generated in the 'OUSERMGR.REGISTERUSER' method. Clearly I must have bizobj's looking for my development folder but for the life Of me I can't figure it out from the executable.

I need help here. I've looked at every class, every property, every method. Nothing looks as if it's hardcoded to my D: drive. aaah boy...

Thanks in advance...
