Fixed Page Width Displays Differently on Another Monitor

Hi

My site displays fine on my PC in Internet Explorer and Firefox.
On my wife's PC in Internet Explorer (Firefox is fine) the page is displayed with white on the right hand side of the sidebox (her monitor is bigger than mine too).

I have fixed my main wrapper width to 906px and have my sideboxes set at 150px in admin.

My site can be found at http://www.imagocollections.com.au/index.php?main_page=index&cPath=1

Any help really appreciated (it's hard to troubleshoot for me when it looks good in Firefox:smile:)

Thanks

Craig

Did you get this fixed? I checked on a 1680px wide monitor in FF, IE7 and IE6 - no strange spaces ...

Hi

Thanks for checking this out.

Still no good. It's a new laptop running Vista. I've tried updating her IE and changing her screen resolution - still no good.

Was wondering if fixing the centre column width might help (if so how would I do this?)

Thanks

Craig

I've tried fixing the centre column width in the stylesheet but it didn't help. Any ideas?
