Yes, it was available in 'Add Remove Programs' and I removed it. My Logitech Bluetooth wireless keyboard and mouse still work fine after re-start so I guess I don't need Logitech messenger anyway.
I have a few questions about some of the software I'm using so I'll be posting those in the appropriate section sometime soon, if I ever get a night off work {working 7 nights}.
Well, thanks again to this board and for your time an expertise!
