Yep, thanks, that (and adding :LANGUAGE :ANSI-C) did the trick! I've uploaded 0.9.4 which should work now. Could you please test? I'm a bit in a hurry because we're moving to a new flat on Wednesday... ) Thanks for your help, Edi.

I don't see an easy general solution but for the moment I've uploaded version 0.9.3 which offers the following workaround: <http://weitz.de/rdnzl/#*coerce-double-floats-to-single*> You should be able to (temporarily) rebind this variable to T for single float arguments. Well, UNLESS your .NET method's signature contains both System.Single /and/ System.Double. Let me know if that helps or if you have a better idea. Cheers, Edi.

Thanks Jim, I've uploaded a new version (0.9.2) which incorporates your patch. Cheers, Edi.
