Version 1.04 of RB XML-RPC at http://commons.ucalgary.ca/rbxmlrpc will continue to be made available for those users still using REALbasic 2-3.5 and OS X 10.1.x
Version 1.0.4 of rbxmlrpc is being updated to work with the latest version of the REALbasic IDE, which requires migrating code to the built in socket (from httpSocket) and updating to the new Dictionary class (from hash).
