I just upgraded to 2.3.1 & the site tree is acting weird. I started with a fresh install then copied my additional page types & theme over. Added the blog & the ecommerce modules. Then rebuilt the db. I've done a screencast of what's happening in FF3 & Safari 4 on OSX.
When you click on any page in the admin site tree the icon starts spinning like it's loading. It does eventually load that page but it keeps spinning. The tree also gets a lot of space in between each page & the expand icons duplicate. Each page you click on in the tree start loading & the icon starts spinning but never stops even though the page loads. That plus the added space between the pages make it more difficult to use the site tree. Especially once I turn this over to the end user.
I figured that the best way to show the problem was to do a screencast. Here's the link: http://vimeo.com/5159731
If I reload the page it goes back to normal then will start all over again once I click on a page in the site tree. Any thoughts?
