Menu gets reset to ribbon

[developeris]

Sometimes, for no reason at all and without any error message etc. developer resets back to ribbon. I guess it has something to do with several instances opened. Maybe some file is in use or something, but then a dialog "Retry, Cancel" would be nice, instead of trashing the settings.

Not sure if this is related to your problem, but the layout can also revert back to the default if your monitor configuration changes. To change this, go to Preferences->User Interface->Options->Save layout per multi monitor setup
