I think I'm experiencing some trouble with the fonts and typing.
When I installed this 64-bit version of Ubuntu a prompt popped up saying that I, for some strange reason, did not accept the licence agreement concerning some kind of font software and now I have the feeling that my computer doesn't show all fonts.
Second I can type letters like é (copied from a page). Instead of that the ' pops up immediately after pressing the key. The same is for " and ~ etc.
