I've just upgraded to WordPress 2.8, and am having a few issues already.
Firstly, the admin menus don't work. If I try to expand a section of my admin menu using the arrow dropdown, nothing happens. I have to click on the word "Posts" before I'm given the threaded options below it.
Secondly, when I'm uploading images to a post, I am now unable to insert images from the gallery. I am able to go to the gallery screen, but clicking on the "show" option next to each uploaded item does not expand to reveal that image's options.
For some reason clicking on "show" just moves the admin page in the background up & down by about an inch or so.
I've been trawling the forums for a fix, and one said go to Tools > Upgrade > Re-install Automatically - I've tried this to no avail.
Also I have tried this in every browser I have available, including: Firefox, Flock, Chrome, Opera, Safari & IE.
