Perhaps I should have added this.....I have upgraded to 5.2 and I realize 
that there are many additions that 4.2 doesnt have, etc.etc.etc.....that was 
hardly my point!!!!!.......part of what I was trying to say is that I still 
use 4.2 just in case and have found it, at least for some of the things I've 
worked on, to be quite helpful to me in  a way that the upgrades were 
not........naturally, 4.2 doesnt work on every ocassion but I have found 
many instances where 4.2 will work although 5.2 wont or the answers are 
completely different......also, in terms of using , for example, a 
subscripted definition , such as

E_subscript_x[x, y, z] , I have also found that 5.2 handles this quite 
differently then 4.2 especially if you take the derivative of the 
function.....(the subscript is gotten from the appropriate Palette).....in 
fact, I can't use this definition in 5.2....

When I sent these comments, I thought that someone, at least at Wolfram, 
would care and would want to investigate this......if something doesnt work 
in a New Version but does in an Old Version, strikes me as a Bug in the new 
software assuming that the earlier Version's answer was, in fact, 
correct....or, at least, it's food for thought...

or I hope it is....Jerry
