One of our users does have trouble using the spell check in Zimbra 8 webmail on a win7 machine, either in IE, firefox or chrome. misspellings or not recognized words are coloured as they should be. hitting the right mouse click gives a colour change at the destinated word but no alternatives comes up.
so far no one else experience the same problem and I am not able to reproduce the fault on my own hardware because everything works nice.
does anyone have a clue for this?
