I've always/only been using Chrome and have no problem so it sounds like a setting on your end or the tablet, etc. When you say you cannot log in, what do you mean/what happens? Do you get a log in screen or not even that far? Do you have any trouble with any other sites similar to this one (message boards)? Have you changed any settings, tried turning off and turning on, made sure you logged out and cleared cookies, etc. and that your tablet has enough extra space. Are you sure Microsoft/Explorer isn't getting in Chrome's way, being obnoxious about letting it be in charge?
