oh by the way, thanks for your help Rob....
I have sorted it...
I dont know what on earth has changed but on the arduino code window there is a tick (Verify) and an Arrow (Upload)..
now before i used to just click (Cntrl + R) (Verify and compile shortcut) and that would upload it..... well its not doing that now and i have to use the arrow (upload) button....
Serious Blonde moment going on here..... can i blame it on the man flu ?
