After upgrading to version 23.5 from 23.4.2, my Scrubby Zoom is greyed out and I am no longer able to adjust brush size using the ALT key on my keyboard and dragging the mouse. I heard there was an issue with this upgrade and some NVIDIA cards. I assumed the 23.5.1 update would have solved the problem, but it still exists. Uninstalling 23.5.1 and re-installing 23.4.2 makes things work like they should again. I have reset my Preferences file with no success. Is it time for a laptop with a more recent card? I currently run a GTX 960M card in a Acer Aspire V Nitro laptop.
