Well *cough*, I might have written a couple of dozen tests to check the Objective-C bridge, but obviously if I don't run them, why something broken creeps in. It seems that I managed to make a code change that broke how the unsigned short data is fetched from a objective-c message send. As I was working on the Cog Stack VM for the iPhone today I tripped over the fact that I had somehow managed not to run the test suite. Obviously if I had it would have told me something was busted. I've fixed this and shortly I'll look at building ObjectCPlugin.bundle 1.1.4 and Mac Carbon VM 5.7b2 People who have built their own plugin should fire up VMMaker and rebuild a copy from the latest SqueakSource update -- =========================================================================== John M.
