yeah in game the mouse works fine, it's just the workbench screen where it acts weird
I have an xbox one wireless dongle and a wacom tablet plugged in, I don't think I have anything else that would mess with the input in this way
it looks like my tablet was interfering with things, as long as I don't have it plugged in the mouse works fine for the workbench screen so mystery solved I guess lol
Good to know... I think there's tablet or two around the office, I'll try one out and see if I can reproduce. Glad we got it figured out.
