situation like this:
In main page (sharepoint, used masterpage, page1) , webpart (yellow zone) loads another page (page2).
page2 popup a radwindow (page3).
Will this radwindow (page3) be block in the webpart zone (yellow zone)? or can be moved out of this zone?
And this radwindow (page3) will popup in screen center? or in yellow zone center?
I try popup window from a page which only used masterpage, good effects! But sharepoint+masterpage+webparts, I don't know.
