Try setting the camera to manual and then turning the polarizer. That locks in the exposure so it cannot change with the reduction of reflected light by the polarizer. Once the polarizer is set, change back to the mode you want for shooting. I find the same problem with my camera because as the highlights are brought down, the shadows are bought up exposure wise. This changing exposure makes it much harder to judge the actual changes to the sky.
Brilliant, I never thought of that! I'm glad to see that 'ol lightbulb in my head hasn't burned out yet!
