I don't know why, but my g.chrome can't access the notification bar on Facebook, as well as the other buttons on the bottom bar such as; online friends bar, application bar, etc. I prefer to browse in g.chrome to other browsers, and I don't wanna change that. I just can click those buttons, but can't do further. I can't click links in those bar.
please help me solve it.

and sorry for my english, wish you understand.
thank you.

no one can solve my problem??

Well, I can't help you on that specific problem but I can tell you what I always say to people having problems with Chrome....

Try changing Chrome's Channel to Dev, reinstalling and/or updating.

thank you..it works..
Thank you very much..

any way..what the updates?? I'm mean I've changed it to Dev channel..so what?? what's new?

Well, you get updates faster than the Beta & Stable channels (ie: F11 Fullscreen, drag tabs to the sides or the top to resize the window, manage Most Visited thumbnails, and more...)

Same here no bottom bar visible. Chrome 4.0.206.1
Since sometime ago, but I remember this is only recently.
