Ok... just found out how to solve it:
I had about 10 breakpoints around different program files; I deleted all of them, and magic, the debugger worked fine again.
I just can say that the debugger is not working well with breakpoints; sometimes stops, sometimes don't... sometimes get hanged with them... I have to reset the list of breakpoints from time to time to have the debugger working.
Finding out work arounds for debugger bugs, it’s taking me more time on than to develop my application
