I contacted Autodesk help, and they claimed that I didn't have the most recent version installed, so I uninstalled Design Review and then reinstalled it, with the most recent download directly from Autodesk's website. This has become highly disruptive as I then have to stop working, force quite all instances of Design Review via the task manager, then reopen all of the drawings that I previously had open.

When this occurs I can either see the green 'D' logo in the upper left corner of my screen, or an 'F' in a grey box in the same location, as if someone were using Design Review and pressed alt to access the menu via keyboard. When this started to happen I thought that I had a string of bad keyboards, until I noticed that Design Review is the culprit. DWF format, and without maximizing or using Design Review recently it will randomly take control of the keyboard and not allow the application currently in use to receive any keyboard input.

I will have Design Review running in the background, and I always have at least one instance of Design Review running as I'm constantly looking through drawings in. For multiple years now Autodesk Design Review will randomly hijack my keyboard, and I can't find a way to stop it.
