vbadvanced problem in internet explorer 8

[kh99]

BTW, it looks a totally different way on Chrome...

That's a good one - there are three cells in a table that's 100%, and two of them have width = 175 but the middle one has nothing in it. On FF it expands the center one to fill the space, on Chrome it expands the left and right cells to fill the space, and on IE, well, I'm not sure what it's doing. This is why I never went in to doing HTML...

In any case if there's something in the center cell (even just a &nbsp), it looks right in all three browsers. I think there's a module called "Custom Page Content" you can put there which will only show something if you've integrated the page with one of the vBulletin pages, so you could try putting that module in the center column (if it's not there already, that is).
