I've been beating my head against the desk for the better part of a week trying to find out why my program would not call a javascript function from an ajax postback. I tracked the problem down to GetRadWindow not returning a window. Searching the forums found a couple other examples of people with a similar odd problems with no solutions as yet. The good Telerik folks have tried their best to help me in other forum posts. but this one I fear may be a Firefox issue.

Telerik 2010.1.519.35 - FireFox 3.6

I have a master page which has a javascript function I want to call.
From the content page I open a radwindow which is defined in the radwindowmanager of the master page.
When a button in the radwindow is clicked I want to registerstartupscript so I can call the javascript function in the main page.

This does not work the first time the radwindow is opened, but only in FireFox

If I click the button that opens the radwindow, and then click the button in the radwindow to make the call, it fails, not having gotten a valid radwindow from GetRadWindow. I can click the button multiple times, it still does not work. If I close the radwindow, and click the button to open the radwindow again, the second (and subsequent) times if functions as it should.

If I execute the same code from Internet Explorer it functions properly every time. It's as if Firefox doesn't add the radwindow to it's internal list of windows until after it's been closed (just a guess)

A simpler example with just a webpage and radwindow had no problems, only the combination of master page, content page, and radwindow exhibited the problem for me
