You can see which dictionary is selected if you right-click in a text area and open the Languages submenu.
You can open the "Add Dictionaries" link to install a dictionary if you do not have one.
Also make sure that [X] "Check Spelling" in the right-click context menu has a tick.
I think that u didn't understand me :/
I gave that dictionary problem like example.
I cant open that right-click content menu anywhere.
When I search for some pictures I cant save them with "right-click>Save As..."
because that right-click content menu is not showing I need to drag and drop
picture on desktop.
Did you understand my problem now?
