I use Firefox and I’m not experiencing that problem and I can’t find a way to replicate your problem.
The only thing I’ve experienced that is similar— I had a mouse go goofy on me. It would decide to lock on the scroll all by itself and trying to post, copy paste, highlight—pffft!— a mess.
I kept holding off on getting a new mouse thinking maybe it is something else because things were so strange I thought surely a mouse couldn’t do all that.
I purchased a new mouse and the goofy went away, at least with my browsing. I’m still the same.
Is it a microsoft mouse?
SmokingJoe ~ Say, how many security updates have the Microsoft devices like the Microsoft computer mouse or keyboard or the XBOX 360 ever had (bear in mind that Microsoft has been one of the top computer mouse makers on the planet for DECADES).
