When set to use an internal clock (atmega32), my app works ok. 

When set to use an external clock (fuses CKSEL = 0000 and SUT = 10) the 
chip does nothing. I assume I have something wired incorrectly. 

I'm using this external clock:

I have it wired like this: 
pin 1 floating. 
pin 4 to ground. 
pin 5 to xtal1 on the atmega32. 
pin 8 to voltage. 

Does anyone have any sugesstions as to what I may have wrong? 

Thanks!
