GridScrolling: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

[Russell]

IE 6 SP2
Telerik.Web.UI version: 2008.2.723.20
(Runtime Version: v2.0.50727)

This bug is identical to:
http://www.telerik.com/community/forums/thread/b311D-bdakdk.aspx

except that it applies to the RadGrid (Telerik.Web.UI.GridScrolling), not the RadSplitter.

When an iframe containing a grid is closed immediately after the iframe contents are loaded (but before the DOM is ready?), a race condition can occur where a javascript error is thrown:

Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

The error is thrown from Telerik.Web.UI.GridScrolling.dispose() when:
 $removeHandler(window,"resize",this._onResizeDelegate)
is called before the setTimeout in Telerik.Web.UI.GridScrolling._initializeDimensions() can fire.

Thanks & HTH,
Russell
