Exception raised closing browser windows-'mousedown' event handler can't be removed

[Curt]

I am getting a JavaScript exception everytime I close a window containing my Telerik combobox hosting Web page. Looks like Telerik is trying to unregister a 'mousedown' event handler but the object does not have this handler defined.

My ASPX page includes the following scripts:  jquery-1.10.2.js   and jquery-1.10.2.js
My RadScriptManager has the EnableEmbeddedjQuery="false"
I'm using Telerik version 2014.1.403.45

Any suggestions as to why this is happening?

Hello Curt,

I am afraid, that I was unable to replicate the described problem locally. Could you specify the browser, under which you had encountered the problem? In addition, it would be very helpful if you could submit a support ticket, along with a runnable sample attached replicating the problem.

Regards,
Nencho

I am having the exact same issue after upgrading to Telerik 2014.2.724.45 FROM 2010....

After closing a window that pops up from the main window I get the following error:

It seems like the control that is possibly causing the problem is  some modal Spell Check. The id is id = "consultPanel_ctlSpellModal_SpellCheck"

Hello Alfonso,

As we are not aware of such issue, I would like to ask to provide us with the implementation that you use at your end, so we could perform some local tests and try to investigate the problem. Also it would be very helpful if you could submit a support ticket along with a runnable sample attached, so we could pinpoint the issue and provide you with the proper solution.

Regards,
Nencho
