Issue Details

I am using FlexLogger, LabVIEW NXG or DAQExpress on Windows 7. I experience consistent crash behavior when I perform certain tasks like selecting back and forth between document tabs, adding a new indicator, or selecting the setting Preferences from the File menu. I encounter error TypeInitializationException, or in some cases I see FileFormatException error.
