Bill, thanks for confirming what MathAction does. Actually, I simply did not 
notice the "Click refresh to recalculate all" and now that I am aware of the 
difference between edit and add comment, that should be ok.  Prior to your 
upgrading preview for comments, I seldom use add comments, to avoid 
broadcasting too many editing changes after save. 

In order to present a consistent page, there should not be this difference. I 
think any time someone press "save" (or even "preview") using "add comments", 
the entire page should be recomputed. (I know this is less efficient, but it 
would avoid treating potentially unintentional wrong results as correct (since 
when a viewer reads the page, the same error remains until page is refreshed). 
And we did a lot of minor editing that would recompute anyway (even though very 
often, the axiom code was not changed).

Now I don't know what to do with the "wrong" but correct answer to 'gcd(p,r)' 
because it is now recorded with the correct result (after I did a refresh)! 
Probably just erase the whole thing?
