Check that your "js" folder off of your public html directory has correct permissions, and that no js files are missing. This can cause issues with admin display sometimes.
Also use developer mode in your browser (press f12), and check console tab when reloading the main admin page to see if any JS errors appear.
Also clear the Magento cache to make sure no old cached files are interfering.
A patch, if installed correctly, should not cause this behavior.
