Ok. I wondered if it could be a threading issue. (We call ScrollToLine
from within our thread.)

Have you another suggestion as to how we can get our script to scroll
the output window without blocking Wing whilst the subprocess is executing ?

Maybe GTK has a way to invoke callback functions on the main thread ?

All the best,
