Our users are currently running Win7 Professional (32-bit) with Office 2007. Lately, a handful of users have reported at random times that they cannot open a Word document. When I further investigate, it turns out that you cannot even open Word itself. When you open a document, Word pops up like it's about to open a document, but closes 1 second later. When I attempt to open Word before opening a document, the same thing happens; Word pops up for a moment, then immediately closes.
