A1:	The key application environments in Mac OS X are Native, Java, Classic, and BSD. The differences among them are as follows: Native For applications that are designed specifically to take advantage of all the features of Mac OS X. Java Java is a cross-platform application environment, which allows developers to create applications that run on multiple operating systems. Classic The Classic application environment lets Mac OS X users run applications built for Mac OS 9 and earlier. BSD A UNIX-style environment that allows Mac OS X users to run command-line based tools and utilities.
A2:	To force quit an application, you can use the Activity Monitor utility to quit the process, Option-click the application icon in the Dock and choose Force Quit from the pop-up menu, or use the Force Quit Applications window. The Force Quit Applications Window can be opened by pressing Command-Option-Escape or by choosing Apple > Force Quit.
A3:	Try a different document; try a different user account; force quit; reinstall the application; remove application support files (for example, preferences files).
