[SWFObject] fp9 bug in IE with multiple swf files + externalinterface (out of memory)

[Geoff Stearns]

we have been working on this today... we have a fix.

it turns out there is a function called __flash_unloadHandler() -  
that does almost the exact same thing that my cleanUpSWFs() function  
does (makes sense because I was e-mailing with a Flash Player  
engineer about the streaming issue (which this is partially related  
to) and they ended up putting code similar to my fix into fp9, only  
it looks like the adobe version doesn't work so hot...

anyway, here's how we fixed it:

changed the cleanUpSWFs() function to fire using onbeforeunload  
instead of onunload - and inside the beforeunload, we remove the  
__flash_unloadHandler() function, so that it won't cause the out of  
memory error.

attached is the version with the fix in it... if you all could test  
this out and let me know how it looks that would be great.

i uploaded it to the test files pablo provided and it looks like it  
fixes it... so if a few of you could verify that, it would be great.

here's the test files with the new js file:
http://dev.deconcept.com/etc/outofmemory/

in ie6 i get no crash and all seems fine.



for the adobe people here:

the difference in your code and mine is that mine does a  
getElementsByTagName('OBJECT'); and then loops through only those,  
and your code has a variable called 'embedded' that is looped through  
- not sure where the embedded var comes from, but it looks like maybe  
it was much more stuff in it that is really needed...
