Comment 4 for bug 651586

Hi,

Firefox and Thunderbird both offer the dictionaries installed on the system (which I believe is correct). It's not really obvious what the significance of the greyed out entries are in gnome-language-selector.

As another example, if you open gedit and go to Tools -> Set Language, it will present you with the same list of dictionaries installed on the system (just like Firefox, but in a dialog rather than a menu).

If you want to hide certain languages in the spellcheckers, then gnome-language-selector allows you to uninstall these components (Install/Remove Languages, and then uncheck the Spellchecking and writing aids checkbutton for the languages you don't want to see)
