Anyone ever run into this....
I'll go and open a file and I'll rename a drawing file while in that dialog box. I will then open the drawing I renamed or any other drawing and work fine for awhile. I will usually crash within that session at some point.
Try this, close all your drawings. Open a new drawing. Run the recoverall command and select the drawing that you rename. It will run thru your drawing (or drawings if you hae xrefs) and check for errors. I would also run the -PURGE command and purge out the Regapps..
Why not just open the file and do a "saveas" instead. You will be working in the new named fie. I rarely have any problems with this.
