Greetings,
please check the video - I don't even get it why this happens, let alone why sometimes program crashes, and sometimes even whole PB IDE disappears or gets killed, leaving only debugged program hanging in Process Explorer.
While leaving debugger out of it, program runs fine (even with POSTing via CURL, getting data back, bla bla bla). I couldn't pinpoint it to smaller scale, though, but if Fred and team are willing to take a look, I can provide whole code (though, I repeat, it's nothing special).
