I think that the one set of changes should improve horizontal scrolling 
as well - the basic problem is more with drawing and event handling than 
the scrolling mechanism. Unless you mean scrolling a horizontally 
oriented list, which is something I have thought about but not tried. 
Does that sound right? If I've missed a case I'll be happy to look at it.

The changes to the event handling were more invasive than I first 
thought so I will be giving them a good test drive before I send a new 
version. In particular I've refactored MorphicEventHandler, which I 
think is probably a worthwhile change in its own right. There were three 
nearly identical submorph scans, which I've managed to consolidate to 
one method. Then its easy to override the submorph scan strategy if a 
morph has a better way to do it.
