There is something wrong in portable version, cause when you click to manage extensions, it goes to page chrome://extensions but nothing shows, so it's impossible to properly manage installed extensions.

Hello oldhouse,

You are right.
Are you on Windows Seven ? (not only this OS)

Issue is reported here (build 40102) and here (build 40091)

No I am running chromium under windows vista 32bit.
Thanks for pinting me to the bug, it seems a problem with original file (and looks like a major bug to me)

oldhouse, see issue comments, the issue is not seven related. It was also reproduced under Linux and Vista.

Just published the new release of chromium !
It solves extensions problems

Thanks for sharing this.
