I've been running into this error when running a VM on my second monitor (with laptop in docking station) and also today when running a VNC connection to another PC in the office. Hoping someone can help solve this. Reinstalling isn't a viable option right now as it's a company PC, we don't have an imaging solution set up yet, and Office 2013 is a royal PITA when it comes to extracting license keys for a reinstall. I need to at least try to fix this one in-place. Many thanks!
