Hover over problem

I have managed to fix this problem.

When you upload a new photo and go to the “Manage Galleries” page there are 2 boxes displayed.

The top box is the “Alt & Title Text” the bottom one is the “Description”.

This “Description” box is always blank but if you click inside it, a space is automatically added in the picture, this is the reason you get a tiny little box appear when you hover over the pictures, simply remove this space, refresh the page and the hover over should be gone.
