@edgarblythe,
If it's the same problem that I have had with AB, I noticed that their server gets constipated and does erratic or non-responsive action issues at times. I've had something like that happen...though not too often.
I've had the bomb go off in the sling due to double-triggering of the mouse.
You have recently bought a new mouse, I seem to recall, Right?
If you're having the problem of first click non-response without being online in Word or a text editor..that is a much different matter than the other, perhaps.
I'm uncertain as to how to advise you - other than try a diff kybd.
Can you borrow another keyboard and try it (without having to purchase)?
