Thanks..ctl-f5 worked a treat..

What I mean by 'too cute' (not very helpful description sorry ) is that I was trying to get as much money into the pot with Villian folding so thought 1/2 pot cbets were better than 3/4 pot cbets. I realise now that I should just stick with the standard 3/4 cbet and get ready to shove on the river. Also, though its only 2nl there are regulars around who may start to read this if I change my cbets sizing depending on my hand. When you have the nuts on the river, then you want to try to bet the max that Villian will call.
