Hi Maciej,
By design, the first RadWindowManager which is rendered on the page is used by the global methods like radopen, radalert, GetRadWindowManager, etc. In order to cover your scenario, you need to upgrade to recent version of RadControls for ASP.NET AJAX. Using the recent version of the RadWindowManager control you can find the RadWindowManager and call its oManger.radconfirm() method explicitly:
Please note that this solution will not work with RadWIndowManager for ASP.NET.
I hope this helps.
