I request a copy of your program for linux.

it doesn't exist for linux. only for mac and windows. the compiler i use -- realbasic -- can indeed produce linux programs, from the same code that produces the mac and windows apps, so it is possible for me to make linux apps as well, if there should be demand for them. but since i don't have a linux machine to do any testing, it wouldn't be a good use of my time to pursue that now. but if anyone wants to be my linux alpha-tester, just let me know. i'll feed you a succession of programs, starting with "hello world" and working from there, to bring the full range of my programs to your o.s. -bowerbird
