highlight problem on IE8/IE9

Dear Sir,

Please find attached sample to reproduce the issue.
When click on the link, there will pop up a window and inside it there is a grid.
You will find that you can highlight the text 1111 but not for the others. this issue is find in IE8/9 but not in other firefox or chrome. Any help to fix this?

my version is

dhtmlxSuite 2010 Rel.1 (DHTMLX 2.6) Standard edition build 110318 (with IE9 beta fix applied) + dhtmlxChart 2.6.5
test.zip (931 Bytes)

This issue confirmed and will be fixed at the next version of dhtlxGrid.

To fix this issue following code to your sample:

grid.obj.onmousemove = function(e){ (e||event).cancelBubble=true; return true; };
