Wireless apple mouse wont allow scrolling on main screen
THis is the 3rd time I've posted re this & no-one has replied!
The mouse occasionally moves the cursor on the main screen but only upwards which is no use, otherwise I have to use the side scroll bar as it won't work on the main screen. This happened before & then it miraculously corrected itself- now it's gone again.
I've got new batteries, cleaned it, checked the preferences & it is very frustrating. PLEASE HELP!😕
