I'm sure this would be a nice and useful module if I could get it to work. There are no instructions for beginners. I assigned the module to a new and empty module position. I added the new position to my template - and I get a link that pops up a nice but empty window! If I then assign my mp3 player to the same module position "mp3" nothing happens. I see the mp3 player module and I still see the link text and it opens a nice new window but not with the mp3 player module inside of it. I'm sure it will be great to use when the author explains how to use it! The help page - http://extensions.joomlamarket.de/index.php?option=com_content&task=view&id=34&Itemid=60 - does not explain anything. It would really help if authors could give a dummies step by step guide when releasing their great work.

You have to have an unused module position for this to work. For example, I wanted to put my login module in the popup, but the login module shares the "left" position with a couple of other modules. Move your target module to an unused position, then point the jm ajax popup to that position. I would have given this an excellent rating if it allowed module insertion by ID.
