I just started having a similar issue. When I open Word I see Document 3, Document 2, and finally Document 1 flash quickly and the 2nd and 3rd documents (and they are named this) go away leaving just Document 1 open. When I compose an email I see a screen flash and shut as well but it's so fast I can't tell what it's really doing. This just started happening and I also am at a loss as to how to fix it. Any help would be appreciated.
