Well, could you elaborate here a little bit, please? Is that only Windows View capability??? Is it applicable to 'odbc e.g. too? Or just only View stuff? btw: is ability to generate own events coming with next release?

Well, I am not sure if I am right, but I tried together with my friend, who is fluent in C, to implement small piece of code, which modifies face data directly in memory, and it works. So basically, once you send your image referring word to .dll routine, you can manipulate its data directly in native level, and once you get back to Rebol, you just need to re-show it. It works, and is fast. As image effects are just data manipulation, maybe we (rebol community) could even create some effect library, which could be relatively easily compiled to support Rebol on most if not all platforms it is available for? -pekr-
