Thanks for your help. However, I think there might be an issue with the Android version.
There is only one settings menu and this is on the main Palringo tab. It only has the three options as above.
I cannot see any other 'settings' in the program.
I have looked at this on the IPhone version and can access the needed settings.
I gave it a go but I will have to try anothr IM program.
Good Luck.
