I have a slight problem with my companies AutoCAD 2008 freezing up after I reload an x-ref. I go to my X-ref drawing and make my change and when I come back to my drawing and am asked to reload that particular X-ref. When I do reload I am asked if I am sure I want to do this and of course I say yes and at that time my entire PC freezes up on me causing me to "control alt delete". Has anyone else with 2008 experienced this problem?
