I'm in the educational field and we have several people who want to use GO-Global UX with their Mac OS X machines. My boss tried running GO-Global on OS X version 10.2 but it locks up. I noticed you were using 10.3... mabye I'll ask him to upgrade. There ought to be a way to map the problem keys, maybe via a .profile change on the unix host.
We all want to get rid of our windows machines but we can't until we can find a way to get GO-Global to work on OS X. The document at
http://www.graphon.com/products/GO-GlobalforUNIX.shtml is a little misleading when it says: Using a Java applet, a browser plug-in, or a tiny native client, you can run your heavy-duty UNIX applications on any network-attached device, regardless of platform or operating system.
