In Ex2_04, the escape sequence \a is used at the end of the text to produce two beeps from the PC speaker, everything was fine except I did not get the 2 beeps. Possible reasons?

Also, I have noticed that if I run the program using shift=F5, the output remins on the screen until I hit a key, but if I run the executable from Windows Explorer the the output appears only briefly and disappears, it doesn't wait for me to hit a key. If I start a command window from the directory containing the .exe and run it, the output waits for me to hit a key. What is the difference here?

One final question, there doesn't seem to be a button in any of the menus to run the program, aside from the start without debugging button in the debug toolbar, is that the only way to start the program other than the ctrl+F5 or through the menus?
