Hi, this is a known anomaly with some ATI cards. Graphical errors on
buttons. I think I remember reading that the best solution was to change
from using the default "Human" theme. This can be changed by going to
SYSTEM -> PREFERENCES -> THEME. I don't actually have the problem myself
but I setup Dapper on a friends laptop and ran in to the issue a long
time ago so perhaps I'm no accurate, but worth giving it a try.
