Arrow keys not working in Safari
The arrow keys on my external keyboard (Macally) stopped scrolling properly in Safari a few days ago. Press the upper arrow and I jump to the top of the page. Press the lower arrow and nothing happens. I can still scroll effectively with a mouse. And the keyboard itself is fine. I connected it to another MBP with the same updated version of Monterey and it works. It also works in MSWord, TextEdit, Crome and Firefox. I have not installed any new software recently.
I tried rebooting in safe mode but the Safari problem is still there. I also reinstalled the system software but to no avail.
I also noticed that if I enter text manually on sites in Safari, it will accept the first word but no spaces after that. It will only accept a sentence or paragraph of text created in another programme and then pasted into Safari.
What is this all about? Any help would be much appreciated.
