Did they have an altercation earlier, who Knows? I suspect at this 
point both of them feel perfect justified in hexing the other.

zgirnius:
There was no time to have an altercation earlier that day. The boy s 
lived in different dorms, and spent their whole morning taking the 
DADA OWL exam. Not to mention, that if James had some recent 
grievance, why did he not offer this to Lily as a reason, when she 
asked him what Snape had done to him?

But that really is not the point. I don't doubt James and Snape had 
probably hexed each other a numnber of times based on the 
descriptions we are given by other characters of their relationship. 
The Worst Memory incident is just not in the same category. It is 
such a deliberate thing. the way James and Sirius take turns casting 
spells, the casual way James jokes with Snape lying at his feet, ans 
the final threat (especially if it was carried out) are just not the 
same as taking magical pot shots at one another in the hallways.

Animagus? Since they were both in the first Order I suspect that at 
the very least Dumbledore knew. I would also imagine Dumbledore had 
known since Sirius told Snape about the Williow.

zgirnius:
Ceridwen is right, Dumbledore says so himself. At the end of PoA, in 
his conversation with Harry, Dumbledore states that (paraphrased, my 
book is hiding from me) the Marauders' learning of the Animagus 
transformation was an impressive achievement especially as they did 
it under his very nose without his knowing.
