Hi, I have made a post about "Windows programming then and now" to the "Anything Goes" topic on the CoCo Forums. http://coco.randomrodder.com/forum/viewtopic.php?p=152#p152 I hope it might be useful to someone someday. I am relying on old memories so update me if something is not right. It spans the time of the CoCo to the future. SHF
