I got the same exact problem with the IE 8. I have constructed a template of my own and it works fine on IE 7 and on IE 8 it only show the last part of the sidebar and the footer.
I have applied the fix suggested above and it works, but the user has to hit a button on the url bar of IE 8. If you hit the button of compabitility, it works properly.
It would be awesome if there was a direct fix for this.
Any suggestions?
