I purchased fb^4 release 3 on July, 2006. I'm trying to install the program on a macBook that I just acquired. Howver, I keep getting the following error message: "The following toolbox items are not available on this computer. This program may crash if you continue." Toolbox items listed are: calloc, close, fcntl, fgetc, free, .... read, realloc, write. I'm thinking I need to visit the Staz page (stazsoftware.com), but that web page seems to be down at this time. I have repaired permissions, moved the dmg file onto my drive before opening, opened the dmg and moved the files into a folder. I also searched my futurebasic@... messages. I noted that some people had problems with compiling applications. I cant even get FB to open without errors. Anyone else experience this on macBooks? Do I need to wait and visit the Staz page when it opens? Is there a patch that I can use in the meantime? Thanks in advance for your help.
