I'm having an odd problem with XSI. Earlier today, I was able to unselect points by clicking on another, and selecting multiple by holding Ctrl. Though, now, for some reason beyond me, it won't unselect anything, even after I go back into object mode by pressing SPACE. Any ideas?
EDIT: It seems to have changed after I installed the plugin for Half-Life 2.
