On my windows xp home system PLT DrScheme opens files twice. I am already 
accustumed to type clt w after entereing DrScheme by opening a .scm or .ss file. 
PLT Schme version 371 does a correct job of debugging, in principle, except that 
every time I hit the step button a new tab is opened and I have to type ctl w in 
order to return to the tab that is being debugged. Yes, it is a little bit 
annoying, but in everybother respect PLT Scheme is great.
