Java Web Start

I've got a jar file that I'm loading with Java's Web Start. When I load the
..jnlp file from a browser, the application installs and runs properly the
first time. If I close the application and click on the link in the browser
a second time, the Web Start splash screen loads for 15-20 seconds and
disappears without launching the app. If I delete the application from the
Web Start utility it will again download and execute the first time but not
subsequently.

Web Start is configured to "Use Browser Settings" under Network Settings.
I've tried Direct Connection also. The results are the same under Mozilla
Firefox and IE 6.0. JRE's for 1.4.2_12, 1.5.0_06 and 1.5.0_11 are installed
with only 1.5.0_11 enabled currently.

Any thoughts?

Thanks,
-Keith
