Dreamweaver very slow on Windows 10 with latest version

Hi all,

I'm finding code editing etc VERY slow on Dreamweaver - anyone else? Like, I type something into the code then thereis a PAUSE and various things underline and then it responds again.

On Windows 10, with latest version. (20.2, build 15263)

My machine is an AMD Ryzen 9 3900x (3.8Ghz) and I have 64gb of RAM, so that shouldn't be the bottle neck - am I'm running off very fast SSDs (NVME).

I've turned off CODE HINTS as much as I can. What else can I turn off? I've tried also turning off Live View - changing to Design view. Is slightly faster but not much.

toby
