Hi Robert Strazzarino,
Thank you for your question. I am glad to inform you that we will make the advanced form show as a modal popup window for Q2 2009.
Although worarounds are possible meanwhile, I would not recommend you use them since the solution could be not very neat. For example, you could have a hidden scheduler which you open in advanced edit mode in new window. This is similar to the RadDock example which you have seen, but you need to place another instance of RadScheduler in the content template of RadDock and bind it to the same data source as the original RadScheduler.
All the best,
the Telerik team
