I'll explain problem details which it occurred yesterday:
my Safari browser shows only the same page when then problem occurred; it was been caused from to scroll from right to left (or left-right) on magic mouse, I could click on bookmarks/address bar but I cannot write into google box to search text.
It liked Safari screen was frozen, something click on reading list/bookmark cannot change page. I was able to quit from browser correctly. I restart browser more times and as soon as I start to scroll with mouse or trackpad, Safari had problems.
This morning I turn on my MBP with no strange behaviour.
I'm amazed, I thought Apple is stable system 😉
Can you help me to give explanations about this anomaly please?
