Did everything just work when you upgraded, or did you have to first set :SURAFACE-ALPHA T on your offscreen surface? I would have expected the latter, or the rules SDL uses for surface blits would not have copied the ALPHA component across. How do you create your offscreen surface? Unfortunately the documentation has remained static while the code has changed. Have to go back and clean that up. - Luke _______________________________________________ application-builder mailing list [email protected] http://www.lispniks.com/mailman/listinfo/application-builder
