sprained my site (not broke, just sprained)

I moved my site from a subdirectory to the root directory. I developed the site on WP v3.4.2 but the root directory has WP v3.5 (not sure if that’s relevant but just in case) and now I’m having some troubles with my pop-ups.

1) can’t open the widgets to change them or do anything to them. when I hover over the dropdown I get: http://mysite.com/wp-admin/widgets.php#available-widgets (but when I click on it nothing happens)

2) can’t upload media in a post or anywhere via the dashboard. when I hover over ‘Get Media’ I get: http://mysite.com/wp-admin/post.php?post=963&action=edit# (but when I click on it nothing happens)

3) cannot change post dates. When I hover over the ‘edit’ button I get: http://mysite.com/wp-admin/post.php?post=963&action=edit#edit_timestamp (but when I click on it nothing happens)

Is this a bug in the new version? Is this a javascript issue? Should I reinstall js files/folders? from old version of wp or new?

Any help or guidance would be most appreciated!
