Viewing and Enabling Breakpoints

If you set more than one location breakpoint on a line, and some breakpoints are disabled while others are enabled, a gray dot appears in the left margin in the Source window, Disassembly window, and/or Call Stack window (not the Breakpoints dialog). The first time you click the Enable/Disable Breakpoint toolbar button, all breakpoints on the line become disabled, and the gray dot changes to a hollow circle. If you click the Enable/Disable Breakpoint button again, all breakpoints on the line become enabled, and the hollow circle changes to a red dot.

An asterisk (*) in the breakpoint check box indicates that the breakpoint is not supported on the current platform.
