Have it in tool bar on five different pc's, all seem to have stopped workiing, anyone else ?

Cleared cookies all that sort of thing but no go.

There was an update to the spell checker in the last week or so that has added some extra options to the right click menu in Chrome. You might want to check "Right click in text box -> Spell checker options"

been there, cant see anything wrong

Google spat their dummy out a while ago, when they stopped Google tool bar working, suppose it works in Chrome though!

I have spell checker switched on in Firefox, checks as I type, you need to add British English dictionary though.
