OK, well now, the first thing I wanted to do was to test the boolean fix. I can't even import anything now. I go to the Object menu>Import Object. The screen flashes and then all the viewports disappear, and no import browser opens. Note that that's just for Importing objects, and the Load object dialogue works..as long it's a VOB from the library. Clicking on File in the library window has the sanme effect as trying to import, only the screen doesn't go blank, ut rather simply nothing happens except I can't move my pointer around for about 20 seconds.
