I ill share my experience in the last week and how i can solve this problem. I was using the " win7 terminal" or "console" from qtcreator to run and debug a application. I've change in the "run options" to dont use the terminal and print the results in qt creator ide. This solve the problem. I could see that is a issue with qt creator and win7 terminal.
perhaps this can be a issue to be reported.
Thanks for help.
