Are you SURE you have the pinout correct on the New Haven display? It MAY not be the same as the windstar...

I know nothing of Windstar, but I use quite a few Lumex displays, and have recently started using some New Haven displays, and the pinout on the NewHaven that I'm using is NOT the same as the Lumex.

Lumex :

Pin1 = Ground
Pin2 = Vdd
Pin3 = Contrast adjust

New Haven:

Pin1 = Ground
Pin2 = Contrast adjust
Pin3 = Vdd

All other pins are the same except for 2 & 3 being swapped between NewHaven and Lumex.
Can't vouch for the Windstar, but you might want to have a look at the data sheets again?
