I am running Windows Live Mail on Win8 as the mail app shipped with Win8 is awful. One of the account users on the PC has a continuous spell check that operates in WLM, while the other has a greyed-out spell check icon above the ribbon and no functional spell-check facility. This inconsistency has no logic since only 1 instance of WLM is installed on the PC.  It must be remediable, but I can find no advice or solution anywhere. It's as if MS didn’t want us to use WLM and use the terrible Win 8 mail thing instead.
