I discovered Chrome to be the fastest browser after Opera went in some direction I do not like. So Google's baby replaced Opera (I never used Firefox at that time). As I am currently using Windows and Safari is just not fitting in the "environment" I still use Chrome although I recently switched to Firefox. That is because Chrome sucks in some ways it's treating my WordPress admin panel and some other minor things. That really pisses me off because I love the speed and the clutter-free look of Chrome.

Long story made short: Do you know a method to get rid off any theme installed? I was playing around with the themes that came along with the new version and now I'm stuck with something I would like to change to "standard" again...
