+ − 1473
+ − 1474 CAUSE
+ − 1475
+ − 1476 When the F12 key is pressed and the application in focus is being
+ − 1477 debugged, Windows NT calls a function similar to DebugBreak(),
+ − 1478 which executes a hard coded breakpoint instruction. The integrated
+ − 1479 debugger then traps the exception generated by this instruction.
+ − 1480
+ − 1481 This behavior is intentional and occurs with other debuggers such
+ − 1482 as WinDbg from the Windows 32-bit SDK.
+ − 1483
+ − 1484 RESOLUTION
+ − 1485
+ − 1486 While there is no way to disable this functionality, it doesn't
+ − 1487 affect the application that's being debugged other than to pause
+ − 1488 debugging and change focus. You can continue debugging by pressing
+ − 1489 the F5 key.
+ − 1490
+ − 1491 This can be annoying if you have an application that heavily uses
+ − 1492 the F12 key, so you may want to temporarily assign another key to
+ − 1493 handle the F12 key functionality in your program when debugging.
+ − 1494
+ − 1495 STATUS

+ − 1497 This behavior is by design.

+ − 1515
+ − 1516 The key specified in this value only sets a breakpoint. It does
