Today I upgraded to the latest version of Safari for Windows, version 3.0.4 Beta.
Unfortunately, for some reason it’s completely unusable. I can’t read any of the menus, and the displayed web pages are corrupt.
I guess that’s what “beta” means, then.
Update
I’ve uninstalled Safari, and then reinstalled 3.0.4 Beta but I still get the same corrupt screens.
I’m back to version 3.0.3 Beta and it’s all working fine, so I guess the problem really must be with the 3.0.4 update. Which is a shame.
