Catch a cancelled sign request?

Anyone know of a way to 'catch' a cancelled form signing? In my OnSign() event handler, a signature is manually created and then applied:

Signature thisSignature = e.SignedDataBlock.Signatures.Create();
thisSignature.Sign();

Sign() doesn't return anything, so is there a way to know whether the user cancelled or if they successfully signed?

I am developing in C# on Infopath 2007, but most users only have Infopath 2003. Any help is very appreciated!
