There have been a few members who are having issues with the buttons on the new control panel.

So far it would appear to be users with FIREFOX but let us know if there are others. We have yet to get to the bottom of this problem yet but we are working on it. In the meantime take a look at an extract from the FAQ page on the main site. It might help:

I can't see parts of the site or some of the buttons don't work. Why is this?
   The answer is really two fold but both are to do with the security
   settings in your browser. To get the most from the site your browser
   must be able to use JavaScript and iFrames. Each version of browser
   is different but changes to security is usually found in TOOLS,
   SECURITY tab. You can either change it to a lower security level or
   go for a custom setting.
   
   In the list you should find ACTIVE SCRIPTING or JAVASCRIPT. Make
   sure that is enabled.
   Also in the list you should find LAUNCHING PROGRAMS in iFrame.
   Enable that too or set to prompt(recommended). You may also like to add MyOwnCreation as a trusted
   site.
