Thanks Kyle, that works great.

Now I have a similar problem with SetSystemUIMode(). Even though the  
function is defined for 64-bits, the enums with possible arguments are  
not. It seems pretty stupid to have a function defined but not its  
possible arguments. Is that a known bug? And any way around?

Thanks,
