XCODE 4.2.1 debug mode fails only
I'm developing an iPad application with XCODE 4.2.1. and works fine. But usually, if I use brakepoints, and press the next step button when the flow stops on it, the debug flow goes to the "start" screen (with lines below) and I can never go out of there. If I don't use the brakepoints all woks fine... Any one knows why the debug mode fails? Many thanks in advance.

    0x2090:  pushl  $0
    0x2092:  movl   %esp, %ebp
    0x2094:  andl   $240, %esp
    0x2097:  subl   $16, %esp
    0x209a:  movl   4(%ebp), %ebx
