Debugging is a process. Debugging a program means examining a program's logic and its variables. As you are looking for a bug, you are looking at functions, searching for text, and diving on variables. In the Variable Window, you may be casting a variable's data type, diving on pointers or substructures.

At some time, you may need to get the Source Pane back to the way it was when you halted execution. The easiest way to get back to the PC is by using the View > Reset command. Actually, I don't know anyone who goes to the menubar and selects this command. Instead, they use its accelerator, which is Ctrl+R.

For release 6.4, we've added a Edit > Reset Defaults command to the Variable Window. This command removes many of the changes you make to the contents of a variable window.
