Session Problem In Mozilla

I have encountered a strange problem. I m making a playlist (asx file dynamically) from database after the user selects a few songs from a checkbox list. The data is stored in a dictionary object and is saved in session variable across pages.

This works totally fine and perfect in IE but in mozilla ff/netscape, the code crashes. Actually, if i don't run the media player(not wrting the content), then code runs fine but if i use response.write to c wht's happening, it doesn't write anything but veiwing on page source, the code actually worked fine.

However, the moment, i provide the contebnt type for media player, it crashes showing error that session variable is empty or some other key error which seems totally irrelevant when running IE.
