Using Amaya 9.2.1 with networked Macs

I'm administrator for a couple of Mac labs at a high school near Chicago.
One of the classes taught in one of the Mac labs is web design, and I
thought I'd let the class try Amaya. It installs and works fine in 10.3.9
and 10.4.2, if it's used by a local user. However, we're in a network
environment (a cross-platform one at that), and Amaya doesn't seem to work
in this setting. A student can log in, launch Amaya from the dock, but it
bounces without ever opening a window or actually starting. Is there any
thing I can do to get it to work, or any information I can offer to help
get the program to work in such an environment in a later version?

Sincerely,
John Buell
