When the PLC option is enabled, for safety reasons, if the PC Unit ID has not been configured, we nag the user to set it. The controller will exit the run mode until it has been configured or the user indicates they don't want to see the window again.

The code that cleans up after Die Test was being called at the wrong place. This prevented it from being called if the PLC Communication window was being displayed. Since the Die Test Cleanup did not get called, the code that re-enables the Run input was not getting called, which then locked out the Run Mode.

This has been resolved.
