I have an assembly that has trouble opening a few parts. I often get the Unable to Locate File dialog box. I want to browse for the file, but when I click "Let me browse for the original file," nothing happens. The button behaves as if I clicked "Suppress this component." I've done extensive googling and haven't found anything relevant. I'm running 2013 SP5, Windows 7. I'm not sure when the problem began.

Update: I typed this post yesterday. Today the browse for file window appears and works just fine. I have no idea what's going on. Anyone have any ideas?
