I'm not sure if this is just my computer/browser making it happen somehow... I thought it was my page template so I tried to fix it by altering table widths and the such but nothing changed... mooching around I see the same thing happening on just about everyone's pages. It's just sort of annoying me really cos it's such a simple thing that I can't fix and it makes my page look like I can't code it right. XD (which I can't do really, but you know...)
I'm currently using Firefox. I'm not sure if it happens in other browsers.
This quick screenshot shows it better than I can describe it... ahaha.
