Since upgrading to SW 2013, I have been experiencing issues with making a drawing from a part after saving the part as a .dxf.  There seems to be a bug in the system that locks up the new solidworks document window.  Closing the part does not help, I must restart SW to correct the issue.  Has anyone else had this issue or is it something local on my end?  I have attached a sample part if someone would like to try it out.

I should also note that I did not change any template or system settings between 2012 and 2013, I did not have this issue in 2012.

Thanks, Jackson
