I've applied the updates for Safari over recent days/weeks and unfortunately they haven't fixed the bugs that annoy me the most:
- showing the desktop hides Safari, but it always reappears for no reason
- CTRL+BACKSPACE doesn't delete the previous word
- clicking the icon in the task bar for running Safari doesn't minimise it
Safari is a terrible attempt at being a Windows application. I stopped using it a while ago and I still see no reason to try again.
