RECURRING MACBOOK PRO PROBLEM NO ONE HAS BEEN ABLE TO SOLVE
I've been trying to resolve this problem for a long time and no one has a clue. No one at Apple could figure it out and even requested the machine back for an overhaul. Nothing changed. I was frustrated enough to the point where I was going to get rid of it and so did a complete, painful (I have a lot of copy protected stuff) reinstall and restore. That did it for awhile so I'm back on it. Unfortunately it has reappeared.
What happens is that in the course of typing on the laptop keyboard a blue box appears and surrounds the page or text, especially with anything online, that then mangles any further input so that the cursor flies somewhere else in a document while I am typing, often in the middle of another paragraph and word. In addition you can't make spaces within characters. Worse it follows me and appears in other unrelated documents and is impossible to get rid of. This has been going on over a year (computer is an M1 MacBook Pro) and no one has provided a solution.
I now think it may have something to do with left-handed me. It might be possible there is some pad gesture, or the way my palms rest on the machine, or perhaps an unintended combination of keys. Does anyone have a clue as to what that might be or what causes it?
