One of two identical mice-Hama 00086543(maybe SN) blue maybe be the candidate
I charged batteries ( 2x AA) and no problems yesterday.
Then i bought new ones nonrechearchables. and switched to thes(Blue version of that mouse) and i saw the grey roundshaped sign which contained the second mouse-pointer glued to lower right side.
immediately changed back to yellow mouse. so far so good.
Yes also ran Glary Utilities. removed also last file of mouse driver Rapoo-mouse. it had blocked core isolation which i had to activate in registry. couldnt delete in registry.
next is getting shielded lan-cable 2. had 3m but its defective-loose contact on lan-adapter.
screen-switch will then also reattached. to use second ultrabook
