+ − 1486
+ − 1487 CAUSE
+ − 1488
+ − 1489 When the F12 key is pressed and the application in focus is being
+ − 1490 debugged, Windows NT calls a function similar to DebugBreak(),
+ − 1491 which executes a hard coded breakpoint instruction. The integrated
+ − 1492 debugger then traps the exception generated by this instruction.
+ − 1493
+ − 1494 This behavior is intentional and occurs with other debuggers such
+ − 1495 as WinDbg from the Windows 32-bit SDK.
+ − 1496
+ − 1497 RESOLUTION
+ − 1498
+ − 1499 While there is no way to disable this functionality, it doesn't
+ − 1500 affect the application that's being debugged other than to pause
+ − 1501 debugging and change focus. You can continue debugging by pressing
+ − 1502 the F5 key.
+ − 1503
+ − 1504 This can be annoying if you have an application that heavily uses
+ − 1505 the F12 key, so you may want to temporarily assign another key to
+ − 1506 handle the F12 key functionality in your program when debugging.
+ − 1507
+ − 1508 STATUS

+ − 1510 This behavior is by design.

+ − 1528
+ − 1529 The key specified in this value only sets a breakpoint. It does
