Wing's debugger is a Python level debugger which means that it can pause 
a program when it is executing Python code, but not during a C function 
invocation.  Just as an example, this means that if Pause is used during 
a call to time.sleep(10) the debugger will not be paused until the 
sleep() call returns.  You may have been stuck in a call to the database 
module that never returned.

To debug C code and stop while a C function is being executed, a C 
debugger like VC++ or gdb can be used.  See 
https://wingware.com/doc/howtos/debug-c-cpp for how to use a C debugger 
with Wing's debugger.

Note that in my experience it's rare to need a C debugger unless the bug 
is in the C code.
