RE: Step by Step skips large chunks of code

Hi Scott,

Do you mean that the debugger skips code only after multi-threads start
running? This is a very important information to this issue.

First, in order to isolate the problem, could you please stop running
multi-threads in your application? Check if the problem still remains while
no user created threads running in the application. You could do that just
comment the code to create new threads.

Second, let us monitor the threads in the Threads window. We could fist run
the application. When the breakpoint just before starting multi-threads is
hit, we could open threads window from menu [Debug] / [Windows] /
[Threads]. (The thread menu is only available when debugging) Inside the
threads table, it has thread id, category, name and location. Current
running thread is marked by a yellow arrow on the left side. Make sure
current thread is main thread. Then start stepping code. Check if the
current thread is always main thread.

The reason why we monitor the threads when debugging is because other
thread may hit the breakpoint when you stepping. That will switch the
debugger to other thread, so the main thread will not go on stepping
anymore in some situation.

Is it possible for you to create a small project that can reproduce the
error and you can send me through email?
If it is too hard, could you copy the routine code and thread running code
here or send me email so that I can do some reproduction attempts on my
side? (hongyes@xxxxxxxxxxxxxxxxxxxx, remove 'online.')

Please try to monitor the threads and let me know the result. Thanks.
