There’s something in my preferences file that is causing Eclipse’s auto-complete feature (for Java) to not work.
What do I mean? Well, I work on multiple computers, and I like a very specific color scheme. So, I exported my preferences file from Eclipse on one computer, and I import it to Eclipse on my other computers. The colors look great and everything is nice.
The problem is, something about the importing of the preferences file is causing auto-complete to stop working. This has happened several times, but to figure it out I did the following: I got a fresh copy of Eclipse 3.6. Auto-complete works. Then I import the preferences file, and auto-complete stops working. The suggestion contains no entries.
Here’s a picture to make it all real for you:

This is kind of annoying. Any ideas what could be causing this? I really only care about my font and the colors in the preferences file… If you want to look at the file, I keep it here on Google Code.
Thanks,

In my experience Eclipse preferences only work well within the same minor version (3.4, 3.5, 3.6 etc) and you go from 3.5 to 3.6.
I would take the time to rebuild your preference setup and generate a new preferences file for using with 3.6.
