I have a trouble-ticket with Zbrush Support who initially showed interest in fixing this but they haven’t responded for days.
Note that I have already completely uninstalled all Pixological software and reinstalled 4R7 with no change. I have also ran numerous hardware diagnostics on my system components.
These three videos show part of the problems I’m having with ZBrush:

In these, you can see that masking seems to work normally until I use the select brush to isolate an area. After unhiding the rest of the model, the previously selected area becomes a mask that can not be cleared and only sometimes can be painted over. You may think this is just a small nuisance, but it has caused me a lot of problems. The only workaround I have found is to select the entire model, clear mask, then show all to apply to unclearable mask to entire model - but that doesn’t prevent the issue from happening and sometimes requires multiple attempts. I use masking a lot and this unpredictable behavior is very frustrating.
I am also unable to isolate a Polygroup. CTRL+Shift clicking on a polygroup does nothing. I have to wonder how many other things aren’t working that I just haven’t found yet. I use ZBrush everyday but know I don’t ever want to open it up.
These problems came and went for a few months at the tail-end of using 4R6. Once upgrading to 4R7, they have become much more prevalent and I am unable to get rid of them. Again, I am using a brand new install and there are no problems I am aware of with my system (I built this machine and nothing else is giving me any issues).
