Display Setup

A strange thing is occuring when I save objects.

If you look in the attached pic you will see that the text in the greenbox on one of the items is shifting to the right. Every time I save it, it moves a little further to the right.

Also I cannot get tabs to display at the top properly. Occasionally I have to go in and redo the settings for all the objects as they go blank.

Ideas? This is on a mac using FF and Chrome.

Thanks

Stephen
