Running iMPACT from ProjNav and clickinc X to close the plug-in results in a prompt:
"Do you want to save configuration project file changes?"
Clicking "Yes" does not save the .ipf file. How do I save the .ipf file?
Clicking "No" will save the .ipf file or alternatively run iMPACT stand alone outside of Project Navigator. This issue will be resolved in iMPACT 11.1.
