I operate W7 with MS IE8. For some reason I cannot log in to my ISP account (Waitrose) from my home computer. Message comes up saying invalid user name or password -but both are definittely correct. I have no problems logging in from work computer (also W7 + IE8). I have spoken to the Waitrose technical support but they cannot find the reason. I assume that I need to adjust a setting or two somewhere. Can anyone help?
