Hello Aret,
If you are using such an old version of the suite my best advise is to
download the latest and test with it. The approach shown in the demos and forums should then work for you. You can see how to obtain a reference to the RadWindow in either of its modes in
this online demo. If you are using a version that has a ContentTemplate and this is what you use then $find() is the approach you need, not the GetRadWindow() function.
