I've been experiencing a weird error message in Windows 7 - when I have to enter my email address to sign up for things in various places I get a strange error message saying this is not a valid email address. This happens irrespective of which browser I use (Chrome, Firefox, Safari) and across numerous websites and some applications like iTunes.
I tried typing my email adddress in Notepad, then copying into the relevant place and I was able to complete the registration without this error message, so the problem is not the email address. It's almost like Windows is doing something with the formatting of the address, that my browsers / programs don't like.
I've virus scanned the machine and actually done a complete clean install of Windows 7, but I still have this problem.
Anyone have any ideas what the issue could be???? Be very grateful for any help.
