It was clearly something in one particular user account on the computer (there are several, and only one user seemed to have the problem). Since it's a new computer, I just wiped that user from Windows 8 and started from scratch. Problem seems to be solved. So, as your help file suggests, there probably was something in that user profile's setting folder causing issues, and a clean start as a new user (hopefully) resolved it.
