How to close the program

This question and your other were both covered by FAQs:

[ul][li]How to Exit Directory Opus
[/li]
[li]Problems caused by unofficial patches[/li][/ul]

While your honesty in the other thread is appreciated, it's a bit cheeky to admit that you're using a pirate version and then immediately ask another question, especially one that's almost certainly to do with helping you work around the problems caused by using a pirate version.

This forum does not exist to help people who have pirated Opus. Please don't waste our time and abuse our goodwill on the forum on top of ripping off the time & effort we put into making the program itself.
