To Refresh/Reload:
As per your suggestion,
I have already simplified and fixed my multiple addMainBox functions for my mainboxes the same way my addSideBar function for my sideboxes is called out only once. Ive organized my mainboxes and sideboxes scripts.
Here's my new edited JS ext file. Please inspect it:
http://h1.ripway.com/frolickfriendster/cbox.js
The Randomized box is still messed up.

Have a look at my proffy:
http://www.friendster.com/frolick
I did an experiment. I took everything out of my JS ext file. Left it blank. Then I just added the following:
1. the profiles.friendster.com script on top
2. ajax request script
3. randomized friends script (old) that calls out the addMainBox function
4. addMainBox script
BUT the problem is still the same. The envelop graphic file is still big.

With the experiment, I came to the conclusion that my JS ext was not buggy at all.
I dont mean to say that 1, 2, 3, and 4 above are buggy...because they are working perfectly on your proffy and on Lordheinzz too...
The question is: where's the bug? or Where's the error even if i took everything out of my JS file already with only this randomized friends code in it...
