Where did you get your ScrolledText class? Even the one delivered with 
Tkinter (which is utterly broken and that you definetely shouldn't use) 
doesn't show this behaviour. Apparently, the one you're using is quite 
broken if it opens a new window. The st.pack stuff should create the 
ScrolledText widget in the "tk" window, so you shouldn't have to do a 
rootWin.withdraw().

My advice(s) would be:

1/ Create the ScrolledText with ScrolledText(rootWin) instead of 
ScrolledText(master=rootWin). The "master=" stuff is not needed and can 
lead to problems like yours

2/ Use a better ScrolledText class, like the one in Pmw (see 
http://pmw.sourceforge.net). And I'm quite sure you'll want all the other 
classes in Pmw too...!
