Forms runtime just hangs on startup

Question

When I try to run any form, a blank "Oracle Developer Forms Runtime" window comes up and then nothing else happens. The same thing happens consistently if I try to run from a server with JInitiator 1.3.1.13 (or apparently any server) or with local OC4J instance using JInitiator 1.3.1.9. Other users can run the same forms from the same server(s). The problem started suddenly with no system updates that I know of between working and not working states. OS and browser: XP And Explorer with SP2 (but Forms behaves the same way if I try Netscape 7). Any Ideas...?
Sample Java Console output:

Answer 1

What happens if you run
http://<server name removed>:7777/forms90/f90servlet
Does the test form show?It behaves in exactly the same way: no form shown and Java Console doesn't show anything past that "Forms Applet version". I know that I haven't changed anything in my local Forms Developer/OC4J environment since it was working. I tried removing JInitiator(s) and having them reinstall automatically by trying to run a form and the download and installation worked flawlessly but it didn't help with the problem. I suspect that something in my Windows system is blocking JInitiator but what could it be?
