[SWFObject] SUMMARY: Ongoing 'disspearing swfs'/'out of memory' errors issues

[Geoff Stearns]

ok, I think i may have fixed this - just had to actually look at what  
the temp. fix was doing and make it a little cleaner.

attached you'll see a preview of swfobject 1.4.4 - if you are having  
disspearing swf issues, please try using this file and let me know if  
you still see the issue.

So far using my multitude of collected test pages it looks pretty good.

i'll check this into svn as well in a few minutes.
