That's what I'm doing, but at some point you must click on Classify
for any action to take place, and then you get a blue to red
color ramp whatever you have entered.
In your case, after selecting Linear interpolation, which button
are you clicking? Actually, I recall being able to do what
you say with previous versions, but was too long ago.
(I'm using unstable 1.2.0 on ubuntu jaunty now)
