Dreamweaver 2020 on Windows 10 is extremely text unfriendly compared to DW MX. It is forever taking time off to think about the simplest edit and it moves from display to code ridiculously slowly. I have lots of memory - that isn't the problem. It repeatedly flashes "not responding" and does so when it's closing to. It feels like a good application has been ruined by over-elaboration. What is it doing with my memory? Other things - the Find and Replace function is much worse than previously and no longer integrated. I dislike the killing of anchors though I understand the ID issue. To be brief - you have ruined my straightfroward webwriting experience and jeopardises a big site at www.ricorso.net. Hope your very sorry, Mr Adobe. I'm pretty sick at you.
We apologize for the issue you are facing with code view. We are investigating the issue internally and have found the root-cause of the same.
Please let us know if the below work-around resolves the code view lag issue.
1. Quit Dw and open Registry Editor in Windows (Start menu -> type registry editor OR type regedit in Run window)
