I have an asus K53E series running windows 7. When I type the quotation marks single and double they don't show up until the next keystroke. I can live with it but it is annoying. I switched the keyboard to English US from English Canada but it made no difference - this was suggested on one site on google. The same problem when I use gmail and yahoo email. I use open office and the quotation marks work OK there. Any info you have would be greatly appreciated.
