 You've probably noticed that the display time stops when an application pops up VB's
built-in MsgBox. Although the system timer continues to tick, the timer control isn't
updated every second, nor do other events (such as painting) process. To update the
timer, replace VB's built-in MsgBox with the MessageBox API function.
MessageBox-generated dialogs don't stop the timer from updating, and they allow other
normal processing, such as form painting:
