Trouble with Safari 4 beta and WordPress
So its seems that the lastest and greatest Safari 4 beta from Apple is experiencing some issues with WordPress (at least in OSX – not sure if this also happens in Windows), mainly when trying to add a link to a post message (see here for more details about the quirk).
Several solutions have been proposed but the one I found to work the best is just installing WebKit Nightly builds and update it to the latest version. Hopefully Apple will fix Safari 4 final (i.e. non-beta) some day soon.
