I've had some problems with Google Chrome on my laptop.
I am running a copy of GC from my thumbdrive with no problem and have a copy of GC on my C: as well.
Problem is that the C: copy very often will not open...click...nothing...click...nothing. It doesn't matter if I have the thumbdrive version running or not. I have to uninstall the C: version, reinstall, and then it's fine for a short while...it even picks my bookmarks right back up as well.
Any ideas...getting tired of the uninstall/reinstall game.
