Bugfix with cash till screen, profit summary. The profit summary figures would tally in inconsistent and unreliable ways if there are unsaved bank/float changes on cash till screen. Also if you drill into txn list with unsaved lines on it you'll see weird looking lines like screengrab below (root cause is partial memory corruption while processing unsaved lines).  On saving things fix themselves up. Issue is now fixed for unsaved lines too.
