I always have better luck with the PowerToy local version - download link
buried in the text on that page - in reality.....

(Full Disclosure: Be sure ClearType is on in
DisplayProperties|appearance|effects.  These widgets are supposed to turn
it on, but you know how that goes.  And If your screen is 10x7 or coarser,
or you're on your fifth beer, you might prefer NO smoothing.  And If you
still use a CRT, forget all the above.)

(I always get better results if I make a semi-snap decision, and adjust
QUICKLY.  Repeat the run, if you're unsure. For maximum psychometric
accuracy, repeat when eyes tired or six-pack empty.)
