Thanks for looking at it Artem

Sergey just reported that surprisingly this fix doesn't work well for 
MacOSX 10.6 GUI

So I completely rewrote this fix, making sure it works for both OS versions.
Simultaneous supporting of horizontal and vertical scrolling events on a 
is a nice side effect of this approach.
(awt.ScrollPane on JDK 1.6 supports only vertical scrolling)

Here you are:
