This is probably a more correct patch as it only changes the Pos variables
when it's a buttonpress and the absolute flag is set.
Because the message in event.c that sends this refers to the getcoords function
for it's position data, then the position data is guaranteed to be absolute
thus I added the absolute flag to the message sent, this should not affect
anything else..
You will have to excuse the logic in input.c as I'm working from a beginners
guide to C. I'm a PASCAL programmer by nature..

Thanks for any input..
