It looks like normal terminal to me, could You define normal? Looks like it appears only when target script prints something, but it shouldn't cus I'm using pipes on stdout and stderr.
If anyone is interested I'm using function doPopen from here: http://code.google.com/p/mansos/source/browse/trunk/tools/IDE/src/helperFunctions.py -- http://mail.python.org/mailman/listinfo/python-list
