Copying does work, but regxpcom doesn't (Score 1)

As another poster mentions, copying the plugin files to your moz plugin directory does work.

However, registering the plugin with regxpcom (the prefered method of installing the plugin) fails (segfaults for me, on RHL 7.2). The Windows installer tries to use regxpcom automatically, so that's why it appears to fail.

I believe this is because the xpcom or oji api changed in later versions of mozilla, while the Sun plugin is still using the older version. Obviously things should get better once interfaces stabilise for 1.0
