As of this moment, I am still waiting for Inventor 2013, which is "not responding", after having checked in an I-Assembly whose table contains 896 rows. Vault Workgroups client reports that all files are checked in, but Inventor is reacting extremely slowly. Of the 2 little boxes in the lower right corner of my screen, the right hand number is counting down agonizingly slowly, so I know that Inventor has not frozen. If I wait long enough (and it has been over 20 minutes) it will eventually finish and I can continue, but this is maddening! Anyone else have an issue like this? I'd appreciate any thoughts about what might be happening.
