DHT11 Temp/Hum sensor not working??

I am trying to get some stable readings from the bugger, without luck. Have crossposted several places with no-one able to answer.

My test-code is here: http://mbed.org/users/Njbuch/code/NewDHT11Test/

I am starting to think there is a design flaw in the Grove module??

Can anyone prove me wrong, and prove they have stable readings from the module on ANY platform.
