Receive an error when closing my program built using LabVIEW application builder

[GODFATHER]

When I close my program built using LabVIEW application builder I receive an application error,"The instruction at "0x77fcb1ad" referenced memory at "0x023a0010". The memory could not be "read". Click OK to terminate the program"
I have no idea why this is happening.

This is most likely due to a reference or similar left open. You will experience this if you leave an image undisposed in IMAQ as well.

Check all of your references and be sure you are cleaning everything up.
