Florian, i have done the same tests in Flash 9 with 2.0.7 rev 336, with a book containing around 100 pages in spreadpage format
I start at 37 Mb. After 10 pages, i am at 43 Mo, and at the end of the book around 44 Mb
GOOD JOB Florian.
Now, i have done the same test with my panorama loader, just for one panorama, and job was done quite fine, i destroy all my objects correctly in my loader when the page is no longer visible, and memory is released, fine, very fine Florian !
I will do some tests this evening in Flash 10, my project need this version because i use a special mouse cursor in my panorama player
Regards
