We are having inventor struck up or freeze issue while working in PDS inventor 2012.
Kindly go through attachments and give the reasons of this issue and how to solve this.
Are you saying that the screen goes black? Try changing your hardware setting to "software graphics" (Tools>Application options, Hardware tab). Do you still get the same black screen? Inventor will be really slow in this mode. If you dont, then its your video card and/or driver causing the issue.
