Kevin-- Actually I've learned (as a result of this thread) how to use Stuffit Expander to convert the zip files. But when I put the components in the folders as instructed, it didn't do any good. I followed your suggestion to check out the free stuff utilities section. I found something called Macinstaller that may be the answer. However, I can't get it to work! It installs itself, it has a set of instructions, it brings up the dialog window, but the dialog window doesn't let you follow the instructions-- most of its buttons are protected. I may try to contact the fellow who created the utility, he may be able to help. Oh well...
