Okay, I did submit a Bug Report on this but I want to let everyone else know about it.
Here is the issue:
I log on to Healer and Click to Cure works with no issues, I then log over to my Mage but the Click to Cure settings are still setup for a Healer, so I change the settings on each Detrimental so that it uses Cure Magic and I'm good to go... I go back on to my Healer and I have to change them back to Cure otherwise it does not work, so I'm basically playing tag with the Click to Cure settings, as they seem to me account wide rather than Character specific as stated on the settings window
I hope this is understandable
