solution for telerik is undefined
I struggled for weeks on the problem "Telerik$ is undefined".  I Always got this problem after closing a RadWindow.  But only on my development machine, not in the production version at customer site.

After I bought a new laptop, I hoped the problem would disappear due to complete reinstall.  However this was not the solution.

After weeks of search I found out that the problem is caused due to a DESTROYONCLOSE = TRUE in the RadWindowManager definition of the RadWindow. As soon as I change that to FALSE, my problem disappears.

Hopefullly this is a clue to you guys to fix this problem.

Best regards,
Guy Van Dyck

This can happen if some code has to continue working after the close() method of the RadWindow is called. Usually, when a complex control is clicked or fires an event that clsoes the RadWindow.

Solutions for that are removing the DestroyOnClose property or adding a small timeout around the call to close().
