Mouse only works properly when pressed onto surface
I have a wireless mouse with a USB receiver that has always worked fine until a few days ago when it started acting up. Now it is all jerky and sometimes the cursor moves on its own without me moving the mouse, however, it works fine if I press it into whatever surface it’s on. Unfortunately, I have to press it pretty hard so that’s not a sustainable solution. I tried it on 2 different computers and got the same result so I think the mouse is the problem - is there any way to fix this or do I just need to get a new mouse?
