Their might be a problem with combine java script. set Merge JavaScript Files to No.

For this navigate to system->configuration

Then under Advanced->Developer and JavaScript Settings

Hope this help you.


I also had the same issue, but i also wanted to merge js files for front-end.

So what i did was, i disabled js merge for admin and enabled it only for front-end.
