Thanks for posting this. I revisited an old site that was bugging out and I was going crazy thinking how I could have left such a bug.

Fortunately, my site isn't so dependent on the stage size changing. Has anyone tried referencing displayObject.parent.width ?

Thanks for putting this out there. After reading this I've made a simple JS function which I can call from flash (if the stage.stageWidth comes back as 0) which gives me the divs width and height which seems to work great.

yeah this is a major pain. the problem occurs about 20% of the time in FF3 when trying to capture the stage dimensions after an ADDED_TO_STAGE event.

Ughhh. This is why I hate Information Technology.

I was sizing my chromeless player based on Stage.width, unaware that zero was lurking in the chaos.

I added FlashVars to my AC_RunActiveContent duplicating width and height so I can always get my default stage size, regardless of bunk global variables.

I just spent weeks debugging a Flash quirk. Good luck in HTML5, oh mighty ubiquitous plug-in.

I have added this issue to the SWFObject FAQ (Q21):

Thanks for the heads up, Jed! And thanks to Aral for delving deeper than I did.

aral balkan had a similar issue that he attributes to swfobject (rather than FF or the flash player in isolation), which i note that you're using in your example pages.

I've hit this issue on windows running Flash 9 in the past. I just took it as a flash quirk and coded around it using enterframe like you last sample.

not sure who to blame or if there is another fix.

I was seeing this exact behavior on my Firefox 3.0.5 build on my PC laptop. I am running several plug-ins, which included Adblock 0.5.3.043 as well as Adblock Plus 1.0.1. In my disabling/enabling of plug-ins, I found that Adblock 0.5.3.043 caused this behavior in a completely reproducible manner, regardless of whether I whitelisted the page and site or not. Easily reproducible with both the Weather Channel new local map and the stageWidth/stageHeight page Steven has created.

Disabling this plug-in and substituting Adblock Plus instead alleviates this problem completely. Just an FYI to those that might be seeing this behavior and using that FF plug-in…
