[chuck-users] Mac OS X on-the-fly issue

I'm unable to get the on-the-fly features of ChucK working. I can do one thing at a time from the command line, i.e. %> chuck foo.ck or %> chuck --loop But I cannot do, say, "--loop" followed by "--add bar.ck" to add a shred. The problem is that once I do "--loop" no prompt reappears for me to type in "--add bar.ck", unless I ctrl-C out of it first, which kills the first process anyways. What's the catch? How do I run a second shred from the command line? (I'm running Chuck 1.2.1.1 on Mac OS X 10.4 using the command-line interface.) Any help would be greatly appreciated. --David
