[Solved] AJAX Manager + Grid results in viewstate errors

[DonKitchen]

I have an instance where a Radgrid is being ajaxified via a RadAjaxManager.  The problem we're having is related to the user trying to interact with the grid when an ajax request is being performed and the user clicks on something else.  For example, the grid does not have paging enabled and has maybe 50 rows.  If the user clicks edit for a row and the ajax request begins (loading panel displays), using IE, the user can click edit for another row before the first request completed.  Whent they do this, an http exception occurs (see below).

In Firefox, you can't interact with the grid during an ajax request and this isn't a problem.  It's only when the user is using IE.  Any help to prevent this in IE would be greatly appreciated!

Here's the exception...

System.Web.HttpException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
