If the "dimpmain" div is not at the top (offset = 70px ex), the  
scrollbar will not work properly. You drag it until only one message  
is seen, you drop, and the viewport will have +/- 4 messages..the same  
happens if you pull it down.
This is happening on viewposrt.js line "l = parseInt((y - sp.pos) /  
sp.lh);", because "y" value is wrong, so the number of lines are badly  
calculated. I think this is related with recent dragdorp2.js changes,  
but can't figure out where.
