I’ve never had ANY problems updating yet now I have three issues, two of which severely annoying.
When I click “Password protect”, it acts like a page target and sends me downwards instead of showing me the password dialog.
Then, if you want to insert a link into a post you get the renewed link screen, like this:
If you then insert the link it’s going to take you away from the page (again). Loss of the entire entry if you did not save the draft.
A third problem is when you try to insert a tag. You’ll be typing ‘over’ the message “add a new tag” and when you say “Add” it doesn’t add.
So what’s causing these troubles? After some research: it’s not WordPress itself, but a third party plugin. Grooveshark, yet again (!). So if you have a Grooveshark plugin, you either have to roll back to 3.0.x or wait until the developers release a version of their plugin suitable for 3.1. I’ve currently disabled my Grooveshark, see if they can come up with a new version for 3.1.
