[KLUG Members] Evolution Preview Pane scrolling?

[Bruce Smith]

How can one control the number of lines the Evolution "preview pane"
scrolls with a wheel mouse?  I'm running SuSE 9.1 everywhere, and on my
home computer the pane scrolls half a page.  On my work computer one
click of the wheel scrolls the pane a whole page.  I don't know what's
different, and scrolling a whole page makes it a real "preview _pain_"!

On SuSE 9.0, the wheel scrolled half-a-page for me everywhere (FWIW).
