Dojo multiple popup windows?

Can some one tell me how to open multiple popup windows without freezing the parent window. A开发者_如何学Pythonctually what I want to do is this: I have implemented a Dojo grid. If some one clicks on a cell I want to open a popup window with information in the cell. I have already done that. But the problem I can't click on the grid again to open another popup until I close the popup I have already open. Also I prefer the popup has minimize capability. Any help? I am new to Dojo related development. Thanks in advance
