Through further testing, I found that this does NOT happen in flashplayer 9 for Mozilla (FireFox and Opera). Only in IE. Do you think there is an issue with flash player 9 or is it more likely that the SWF file was not design to clear the memory properly?
Since the player comes from a third party, we hare going to be hard pressed to have them correct it. Is there anything you can think of that can be changed in the code?
Here is a link to the example - [url removed, login to view]
Could we create a new (parent) swf file to which we could pass both the tour player and also the scene files (and param/variables)? Could we use this new SWF to clear the memory used by the previous file each time a file is called into the player? I know that other users have inserted the player we are using inside of other SWF files. I just don't know what kind of control you can implement.
