Heya, so...
I know this is a pretty strange topic, but it's just what is going on 
. I found it just now, this evening, that if you try to play Zynga poker via Facebook, your browser will just start eating up RAM like crazy. Via task manager, I noticed that the browser was eating more than 18GB RAM simply by having one tab opened with Zynga poker running; a single interaction with the tabs would cause the browser to freeze.
I wonder what is the issue or what is causing it... And if it's indeed some bug on the browser, please fix it ASAP. Appreciate it.
