Is there any way to tweak the refresh settings for Assistant ?

I go to the docs for a particular class, scroll down to the thing I'm interested in and BLAM! the page is refreshed (blanked and completely redrawn). Sometimes the scroll bars are slightly moved and I have to move back to where I was. The blanking part is much longer than a flicker although less than a couple of seconds.

It's very very annoying.

This is on Mac OSX (Leopard).
