1. The old refresh string code also update the time/date opcode. But for the reason that time/date opcode updates the string with the same size, so skip the refresh code for it.
2. Also, the clean old string action used save attribute with paint string action which makes the background show abnormal.  Now using the normal attribute to clean the old string.
