I also had one cms version which was noticeably slower than others before and after. I compared notes with someone else who didn't think it was slow (using the same file) but the times for opening, regenerating etc were a lot different from what I had been used to with Icad.

I've just download v6 trial and I see the same thing as you. Very slow panning and zooming in paper space with multiple views in big drawings. No problems when using Autocad. I have a AMD 2400 xp processor with a VIA SG3 graphics card. I've had this problem with every version going back to v3. I hate to buy high performance hardware and not eliminate the problem. Until its fixed its an unworkable product.

Anyone know if this problem will ever be fixed?

I found all of the Version 5 demo's I downloaded were sluggish.

I have only tried the Version 6 from BricsCAD and it seemed faster.
