odd rendering problem in IE8 with a complex table

[Desolator144]

I hope this is just my browser doing this for some odd reason (maybe the dual monitors?) but approximately 50% of the time I hit refresh on this page I made for a customer:

http://atgseries.com/

the GIFs go out of alignment a bunch of pixels. It's a really simple table with absolutely zero whitespace in the TDs and all GIFs. I used slicing in photoshop to make it so there's a lot of colspan and rowspan but I made it as geometrically simplistic as possible. What really tells me this is a glitch is as soon as you mouse over and of the links, it magically renders correctly. Grrrr! So right now I put a warning on the page about using compatibility view to make it look right and tada, it works 100% of the time then. IE7 shows it correctly too.

Take a look and tell me if you know what causes this and if there's a way to fix it or not. I already removed all whitespace inside the table and added a vertical-align:top property to the style of the entire table. That still did nothing. Is there some forced refresh command I can use to basically do the same as mousing over a link? Or is there some different way to do some of the tags that gets around this glitch?
