Jinxes and Curses

This may have already been covered somewhere, but since I don't want 
to go through all 19,258 posts to find out, I'll ask now.

Do we know what the official difference between a jinx and a curse 
is?  It seems to me that a jinx of a playful thing, while a curse is 
malicious.  Is this accurate?  There are exceptions of course, like 
the "Curse of the Bogies" (sorry, don't have my books with me to 
provide exact reference), for example.  Ron says it to Harry (??? I 
think), so that would suggest to me that it is more of a playful 
thing and has something to do with boogers (*bogies* in most British 
held places).  

If I have offended anyone with my lack of reference, I do humbly 
apologize, I'm posting from work and when the phone rings I have to 
answer...darn emergencies.

Michelle :)  YAH!  My first post ever! :)
