hi

This is a css problem.

Put something like this in the theme css(which ever blog theme you are using)

and The top bar will no more hide the theme.

Hope it helps.

btw,you need to have adminbar css in all your themes in order to enable visibility of admin bar.The best way is use import url syntax of css and import adminbar.css from one theme to all the themes.
