Popup alert window moves content page

Hi!

There is a problem that when adding item to the cart and popup alert window is up, it's getting the content page moves to the right on about 10-20 pixels. All browsers are affected exept Firefox. The same thing is going on Hikashop demo site also. Please, advice is it fixable?

Paste the code in the CSS file of your template.

html {
	overflow-y: scroll;
	min-height: 100%;
	-webkit-text-size-adjust: 100%;
}

Yes, it works! Thank you Vio!!!
