I have the exact same problem of being presistently switched to Draft view from the default Print Layout view. But there seems to be a lag time in between ie. it switches to Draft view after a certain time
period. Working on the document (not leaving it idle) seem to not prevent the problem. The screen also occasionally jumps to a different part of the document. It's a bit annoying.
Similarly, I am using Endnote X5, and working while having the Track Changes option on. Please address this bug.
My system: HP Pavilion dm4. Windows 7 Pro 6.1.7601 SP1. Office 2010 version 14.0.6112.5000 (32-bit).
