Alkis, yes you certainly did help out quite a bit with pixel hunting - nice features now you come to mention them. The control system actually works ok without an "action bar". Leaves more room for the interesting graphics!
I found myself with the occasional wrong click however, usually after going into the inventory box and having the wrong cursor selected, but I do tend to do things a little fast.
I'm stuck at the computer number password bit. Ok, I admit I was impatient and only had a quick look around but I appear to have missed something. pm a Hint please?
