See my response to the same point by Neil Hodgson, where I noticed that 
setting to 9999 lines somewhat disables easy scrolling. (I checked and 
it was 9999 also on XP.)

Yes, lets do. I tried to. A person who installs Python on Windows and 
runs Python (command prompt) instead of IDLE is confronted with a 300 
line default. Someone not familiar with Command Prompt will not know 
that the limit can be increased. I use CP so seldom, until recently, 
that I had forgotten how to do so. I fiddled with the history buffer 
setting on the first page. That did not work so I gave up.
