WP Dashboard Issues

Hi,

Sorry if this is the wrong place to post but Im still learning the lay of the land here.

I have an issue where all of a sudden my background in the dashboard is partially black. The font has gone all blurry and thick. Writing posts is a mission due to writing grey on black effectivly.

I have tried clearing the cache and rebooting both the browser and the pc. I have also tried re downloading the latest update of wordpress and the theme.

The theme I am using at the moment is Gamespress and I havent done any plugin or theme updates for a while and they are all upto date. No new plugins have been installed either. I basically wrote a post and published it then a few hours later went back to do another one and this is where I am.

Has anyone got a clue whats going on? Any possible solutions?

Thank you as always

Jim
