Maybe just sort out your damn website, idek.
Right, so I went on looking for a tutorial and stuff, and then I see this /terrible/ website, like there's buttons on top of other buttons like wth are you doing idek but still go sort out your website there's my feedback for you.
Based on your email address, I doubt this is going to get through to you. But I'm going to try anyway...
The website looks good in Chrome, which I usually use. I've also tried it out in IE and Firefox and I'm not seeing the problems you pointed out.
Is there any chance you can get me a little more information to go off of? For example, can you tell me what resolution you're running at, which browser you're using, and perhaps even send me a screenshot of the problem?
I just can't reproduce this error.
