+ − 1570
+ − 1571 CAUSE
+ − 1572
+ − 1573 When the F12 key is pressed and the application in focus is being
+ − 1574 debugged, Windows NT calls a function similar to DebugBreak(),
+ − 1575 which executes a hard coded breakpoint instruction. The integrated

+ − 1577
+ − 1578 This behavior is intentional and occurs with other debuggers such
+ − 1579 as WinDbg from the Windows 32-bit SDK.
+ − 1580
+ − 1581 RESOLUTION
+ − 1582
+ − 1583 While there is no way to disable this functionality, it doesn't
+ − 1584 affect the application that's being debugged other than to pause
+ − 1585 debugging and change focus. You can continue debugging by pressing
+ − 1586 the F5 key.
+ − 1587
+ − 1588 This can be annoying if you have an application that heavily uses
+ − 1589 the F12 key, so you may want to temporarily assign another key to
+ − 1590 handle the F12 key functionality in your program when debugging.
+ − 1591
+ − 1592 STATUS

+ − 1613 The key specified in this value only sets a breakpoint. It does
