Hi Pedro: I also normally prefer to use gdb (the Linux debugger that you are also running from your Linux IDE) for debugging rather than old-fashioned insertion of write statements to debug. Nevertheless, in this special case we likely have a time-dependent race condition between two processes that are running (and just for the case when they are running for the second time too close to when they ran before). So for this special case I believe the old-fashioned debug methods are likely the best. By the way, since putting off the const correctness topic until post release, I feel much more on top of the release process, and I am extremely curious about the cause of this "long pause" issue in case there turns out to be a simple fix. So if I don't hear from Phil by later today that he is spent the required hour himself, I will likely insert sufficient write statements in the -dev wxwidgets code and wxPLViewer code to finally pin down the exact system call that is causing the long pause.
