Try using the F11 key to toggle back and forth between a full screen and regular screen setting

it really makes it easier to see everything

also remember to click the "anchor" symbol (highlighting it) so that you can manually work your scroll bar so you can read back the posts at your own speed

and alltough I dont use the following feature I have heard there is a way to make the avatars disapear so its an all text format which again makes even more room on the screen before it advances
