PAGEUP and PAGEUP work only once in IE8

[ramirez]

Hello.

ExtJsVersion : 4.1.1

I have a GridPanel with around 250 rows or more of data.

Navigating using the PageDown and PageUp of the keyboard exhibits an unexpected behavior in IE.

In Chrome, PageDown and PageUp to navigate is working as expected.

But in IE8 (my workmate said same problem in IE9), PageUp and PageDown works only at first operation then stops working in the subsequent presses.There is no error in the console therefore I assume no JavaScript error is stopping it.

I tried to search around but I cant find any, thus this post.

Same problem is reproducible in the demo site

I hope you can help me. Thanks in advance.
