I'm using the brand new hosted option for CIM (with php) with is very nice.  It's working just fine for me... except one problem - the closePopup function in popup.js never gets called when I click cancel on the iframe form or have a successful save.  I've tried everything with no luck - I don't know if it's something I'm doing or something not firing on the hosted form page.  I'm not that great at javascript, but I tried debugging the script as it ran (profile.js) and it seemed to get to the part where it sends the 'cance' string to the iframecommunicator (which was valid), but then it seemed to get lost before triggering anything in popup.js.  If that makes any sense or you know what the problem is, please let me know!  I need to get this working. 

Thanks.  By the way, I'm using in a codeigniter framework, but I don't think that should have any effect on the issue, and everything besides the popup close is working fine.
