|If you are using something like Windows Live Mail then the browser wouldn't come into it. Which is another good reason why we need to know what email program or service you are using (as per #6). There are stacks, all different, so there is no point us trying to guess.|
If you are using online email (webmail) then let us know what browser you are using too.
As per #3, what type of attachment is it?
Always pop back and let us know the outcome - thanks
