CKEditor 3 not displaying correctly

Hi,

I'm trying to insert the editor into a web app that creates pop-out forms within a set framework that we don't control, however when the editor initializes all of the menu items appear to be crunched up to the top right. I can manage to click on the help icon and this makes visible the "About CKEditor" layer but there is then no way of closing it. The red x circle is visible but it doesn't respond to any click event.

The forms that are created within the framework are a based on an iframe with customizable content placed in the one of the three frames and this is where the issue is occurring.

We've been able to get obout's html editor working within the framework that I've described so I'm hoping it's a solvable issue. If anyone can point me in the right direction for what to look at (I'm completely new to CKEditor) or if anybody has experienced similar and managed to solve it I'd appreciate any help.

Many thanks,

Paul.
