Stopping the screens overlapping when the browser is minimised

Stopping the screens overlapping when the browser is minimised

Hi I picked up a nice script which allows me to scroll the page horizontally instead of loading them one at a time... the problem is when you minimise the page the previous one loads in. You can see this by clicking item 2 and minimising this.

Is there a way to stop this from happening? I have tried some CSS tricks without any success.

Many thanks
