Hi,

Thanks for your response.

FF version: 2.0.0.14
I'm closing the module using the "close module" object, that was automatically added in the template.

I'm not using a standard window, so there is not native close. I'm showing the module in a frame, inside an IFrame. The IFrame page, is the one holding the SCORM API implementation, and the terminate function close the window if called (after doing a commit). I have a button to close the Iframe, and if I use it, I don't get the error (it works fine).
