I has this problem last night I was having a wank and I had the townend open in another window just in case the missus came down the stairs I was mid stroke when low and behold the missus came down the stairs quickly i put the chap away just in time I opened the townend window only to find the citrial error message so there was me looking red faced looking at a blank screen: BUSTED!
Ha ha
That's never happened to me, honest
