Hi Ron, there has been a progress bar for the hidden line generation stage of PDF, AI, and DXF export for the past 2 beta releases now.

I just tested it with the current beta and it seems to be working as expected for me...

Are you trying some other format than PDF, AI, or DXF or possibly exporting a wireframe drawing (with no solids in it) that does not have any hidden line removal generation stage in it?

Anyway there hasn't been any removal of progress bars as far as I know about...
