Hello,  
I’m using some javascript to detect and download the latest verison of flash for a webpage. But my problem is with aligment. I can’t seem to align the flash movie center after the install is finished. I believe my parameters are screwed up but if some one could take a look at it for me it would be a great help.

Thanks  
Cloak
