Anyone else has seen "forrtl: error (200) ..."

Thanks for that hint.

Indeed a extension I'm using in my script uses matlab, and matlab uses (I'm 
quite sure) fortran.

But does that mean, if a fortran dll is loaded, a underlying software layer 
passes Ctrl+C to the fortran dll instead to python? (I can reproduce that in 
doing a ctrl+c while my script is currently at time.sleep(10)

Thanks,
