I've modified the library now to allow me to preload the data that was previously being obtained via a callback, and it appears to be working. I'll see what's involved in getting my changes into the real library, since I don't really want to have to manually re-do them whenever an updated library comes out. It would be nice to know how to get it to fire occurrences so I can get other niceties such as parallel execution with progress metering working, so I'd be interested in knowing how it's done. No urgency though since what I've done satisfies the immediate requirement of generating and validating signatures. -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/
