Web page moves a few pixels when using page transitions, WD 7

I have applied a couple of different transitions to a website, I just made, to play with the effects. After the transition is done the page move a few pixels to the left.
you can see it here: http://jewelallison.com
The "video" page has no effect and does not move. Any idea how to fix this?

Looking at it a little closer. At the start of the effects the page moves to the right, then after back to it's original position... hmm

Checked this in different browsers, so far Firefox and Chrome display this odd effect. IE does not... surprise.

Just noticed this also occurs on Gary's overview page for WD7.

This is because of the vertical scrollbar.

I shorten the "upcoming events" page so it fits on the screen and the page did not move back to the left, but still moved to the right.

Is this because you are going to the page with no scroll bars from a page which does have scroll bars..

If I go from a page with scroll bars to another with scroll bars I get two vertical shifts, one right one left. If I got to a page with no scroll bars I get on shift to the right. This is in Firfox.

In IE it seems to work OK as long as you use the same transitions. If you go from a drop down to a fade you'll get a quick page load in the end.
