A new player to the desktop RIA playground?

With the release of GTalk Lab Ed, an desltop version of GTalk Gadget, Google has showed up its achievement of WebKit engine embedding. After Adobe AIR, Mozilla Prism and some announcement from m$, the search giant maybe also silently joined the Desktop RIA game. Will the gears finally become a Porsche? Let's guess...

"AIR crash"

The AIR(Adobe Integrated Runtime) 1.0b2 for win32 crashed on very simple js/html code.

Setting style.display of an iframe(or its container) element to none is dangerous, the workaround cound be setting style.visibility to hidden.

Get the crashing code here: AIRb2CrashSample.air.

It's even my first AIR program. :|
