Columns all have the same width in IE9


We have an application that uses dhtmlxGrid to display data. Everything works well in Firefox and Chrome, even IE10. But when we switch to IE9, all columns are rendered with the same width and the data in de columns do not line up properly with the header. The screenshot is the result in IE9 (data is blurred 'cause it’s confidential). Can someone please take a look at this problem. I also attached a demo application, I figurred you might need it.We are using version 3.6 for quite a while now.

Unfortunately the issue cannot be reproduced locally.
Your demo works well in IE9 for us.
