The Open Loop Model Option screen in Flashdoctor is shared between the HVAC and Rollforming controllers.

The screen is only constructed one time. It gets displayed or hidden.

The screen was not written with the assumption that it would need to enable and disable all controls, depending on the controller type. It was written with the Rollforming models and options enabled by default. The HVAC file would disable the Rollforning Models and option but nothing short of restarting the program would re-enable the Rollforming contols.

This has been resolved.
