This one's in the faq.  It's a bug on win9x with the popen command.  
On win9x, popen expects a console to redirect i/o to.  In idle and 
Tkinter, there is no console open.  I spent about two days beating my 
head against this on, before i realized it wasn't my fault <0.1wink>.  
The faq sugests some fixes, but i just started using os.system and 
redirecting to/from a file.  Which is ugly, but that's win32 for you.  
The microsoft site also has some info about this.
