Inserting DXF files causes fatal error
In previous releases of AutoCAD, DXF files could be inserted into the current drawing file using the insert command. Starting with AutoCAD 2005, the same process causes frequent fatal errors.
Workarounds: Open the DXF, save it as a DWG, and then insert the resulting DWG
First Appeared: AutoCAD 2005
Status as of 2006 SP1: Still reproducible
Status as of 2009: (unknown)
