Problem with sizing of textarea in lightbox

When I check the demo with this example :
[url]http://docs.dhtmlx.com/scheduler/samples/01_initialization_loading/05_loading_database.html[/url]



The size of the lightbox depends of the height.
On my local server, it doesn’t look the same :

It’s one of the things I don’t understand with IE but this magic line solved my problem:

<meta http-equiv="X-UA-Compatible" content="IE=10,9,8,7" />

Beware that scheduler support only standard mode of IE, it may behave incorrectly in Quirks mode.
