I removed console output by adding these 2 lines in my pro file.
CONFIG += release

Now for debug purposes, I need the log to the application output window. For some reason I don't get log anymore (I have removed the 2 line). I am not sure what has been changed, I comapre with old version it looks fine. If I create a sample file then I get the log. But for some reaosns I don't get log from my current project, Can any body point me what could be wrong?
