IE problem - background image is masked

[hhm]

Hi all!

I have a small problem on one of my websites:

  www.learning-it.dk

The problem appears below and above the menu-module in the left bar.
For some reason IE (v. 6+7) won't show the grey background image correctly. Instead it's masked by a white colour.

Any idea why?

Note: the website is showed correctly in firefox and safari:

Instead of an image you could try this...

#stage-main{ backgrund:url(uploads/images/template_imgs/bg_left.jpg) repeat-y; }  < this will not be needed
#stage-main-box{background-color:#ececec; }
#stage-main-menu{; float:left; width:200px; padding-top:10px; padding-bottom:10px; }
#stage-main-content{ background-color:#FFF;float:left; width:478px; padding:10px; }

Hi Mark

Have thought about that myself and will probably go with that.
But can you explain why IE doesn't display it correct?

best regards
