I have a user that gets a Fatal Error when he inserts a library part from a local library, and then tries to save the autocad drawing (this also happens when autocad autosaves). The error causes autocad to shut down. If he inserts the part from the network, and then saves he does not get the error. The user works at a remote location, which is why we have his library stored locally instead of having to insert all of the parts from our corporate network, which can awhile over a basic cable internet service. Thanks in advance for any input. He is using xp w/service pack 2.
