I just upgraded to 2.0.10… the front end is working fine… I just came across a couple of issues in the backend.
In Admin->Design->Blocks, if I click “+ Add Block” nothing happens. The browser doesn’t think or anything…
The same problem happens in Users->Usergroups… Clicking “+ Add user group” does nothing.
Anybody else having this issue with 2.0.10?
Interesting… I just tried it in IE 7 and it works fine… but it won’t do anything in FireFox.
Ok problem solved… I just had to delete my FireFox cache and let it reload the new 2.0.10 pages
Just like talking to your self huh?

Ya no kidding… I felt stupid after I fixed it 
Clicking the tabs did not work for me after a few visits to the Admin Panel with Safari or Firefox on a Mac. I noticed some missing js files in a given js directory (which was also missing – mystore/js).
https://www.domain.com/mystore/js/core.js
https://www.domain.com/mystore/js/jquery.easydrag.js
https://www.domain.com/mystore/js/jquery.simpletip-1.3.1.js
This js directory lives in an images folder found where your cart is installed (mystore/images/js/), and I simply copied it (mystore/js) and now everything works.
I don’t really know if it’s supposed to live within the images directory or not.
Comments are welcome.
