I have installed the most recent version of Eclipse (version 1.3.0.20100617-0521, build id 20100617-1415) and am trying to install the TeXlipse plugin. I've followed the installation guide thoroughly (although in my build of Eclipse the option was called "Install new software..." instead of "Software Updates/Find and install", but I assume that's because their screenshots are old...) and the installation seems to have gone through fine - no errors, and the Help/About pages suggest that TeXlipse (version 1.4) is installed and working.
However, there are no configuration options available, so I can't follow step 2 of the installation guide, and when I try to open a *.tex document my old tex editor (TeXWorks) opens it instead.
What am I doing wrong here?
