I am working on a new dell laptop, one of the best computers i've ever owned, but photoshop randomly and periodically decides while i'm using a tool to switch back to the arrow cursor. When it does this, I can't zoom in, move, or use any tools, I can only activate buttons in the panels or toolbar, but not actually do anything that affects the image.
It fixes itself if I close all open documents and reopen them, but It's happening quite frequently, and it is interuppting my workflow a great deal.
This has also begun happening to me today. It happens while I am zoomed into the picture and panning. I think I can reproduce it regularly by panning too quickly. The cursur changes from a hand to a pointer and all the tools stop working.
My picture is 131M
Windows 10 Pro 10.0.19041
Intel i7 X990 and 24GB RAM
Performance settings are Memory: letting Photoshop use 13497MB or 60% Cache: default/Photos
