Can't redirect output to a file

[jp31415926]

When I try to redirect the output to a file, the program gets one message, then hangs. The next output is a timeout message.

I suspect it has to do with the "Average DeltaTime" output, but I have not looked at the code yet. If so, perhaps a switch can be added to disable that output.

Command used:
SOTAmatSkimmer.exe -d -c KB0F -g EM64PU -p MyPassword -l > output.txt

Contents of output.txt after a few minutes:
