Yes. I use the CAD Tools plug-in and saw that notice this morning for a new patch AND that it fixes scroll issues.
I may hold off installing newest version of illustrator for a bit longer OR the new CAD Tools patch. But there is certainly a good chance that you and I (jdav7) were experiencing the same issues for the same reasons. Though cut (ctrl-x) and delete (del) were issues I thought I was having... I suspect that each time I did those things, I then scrolled immediately after.
It's nice to know that this might be the fix for the issue. BUT that sucked that I had to deal with that for 2/3 work days. I lost a lot of production time.
For the record. I have continued to use illustrator 27.5 (64-bit) and CADTools 13.2.2 without any freezing.
