[kepler-dev] Re: Can't see context menus in editor

[Matt Jones]

Ned,

This is a known bug and has been fixed in the development tree.  To get 
to work on your machine, either patch the source code and compile (which 
means you can't use WebStart), or I've heard a rumor that the bug 
doesn't surface if you use JDK 1.5.x beta.  There's a page describing 
the problem here, and how to fix it:

Emails about the topic were discussed on the Kepler mailing lists.  See 
this thread:
