All our Explorer users (any version) get this bad error trying to write an email adress within a mail. We are in norway, using norwegian keybord. When users press alt gr + 2 for the @ sign the text gets bold and header1 or header2. Text in the mail gets really big, and no @ sign is inserted. This goes for HTML composing in advanced Ajax client. Did not find this anywhere in bugzilla, anyone heard/seen this too?
