SW 2015, SP1.1

Often (but not all the time!!) when I try to open a file by clicking on the "open" icon and browsing to the file in the dialogue, SW will crash immediately when I select the file (not when I click the "open" button). This can also happen if I'm adding a file to an assembly.

The file will always open fine if I double-click on the file in Windows Explorer, it doesn't matter if SW is already open or needs to open before the file can open. It works either way.

Has anyone seen a similar problem?

I have updated my graphics driver, and I am Repairing my SW installation now.

I have, of course, run SolidWorks RX, but the problem won't happen when I'm trying to record video of it!!
