Admin orders section layout wrong after upgrade to 1.7.7.7

[hennaboy]

Just upgraded to 1.7.7.7 from 1.7.6.5 and the admin has gone a bit foobar in the order section. Looks like the css isnt correct.

Search bar is not formatted correctly. The order status buttons are larger and when I click through to an order all the layout has changed and whilst its not too bad there is definitely the same issue with the date/search function which is throwing out the layout.

Attached is a screenshot of the orders page as you can see the search date calendar is all wrong.

Attempts made so far to resolve are:

Delete of the prod cache to see if that would reset everything.

Turned on/off cache recompiled deleted cache to see if that would reset or resolve the issue but it still remains.

Any ideas?
