local.css

I am really new to running a server. Been experimenting with Pantheon. Everything works great, I have the vote up down module which also works except that when I vote and the ajax updates the number of votes, the page changes slightly, some things stop picking up local.css theming (i use a fusion based theme, acquia marina). This happens only in a few places on the page that i noticed: views external filters and the views pager... What/where could the issue be? what should I check?

Any help would be great, thanks!
