IDA Pro Advanced (32-bit) 5.2 调试windows mobile 6.5程序时，老有这样提示无法完全调试下去！

.text:00084954 MOV     R0, #0
.text:00084958 ADD     SP, SP, #0xE4
.text:0008495C LDMFD   SP!, {R4-R9,PC} ---->这里就出现以下提示

Warning
  IDA Pro could not create a temporary break point for
  the next instruction A temporary breakpoint is required in
  order to suspend the execution after a step. Please use
  F9 to continu the the execution. If you have a hardware bpt
  please remove it before continuing.
  
  程序都没有完全运行完，为什么要用F9?而且我又没有设置硬件中断啊！
