This happens to me in both the 1.0 branch and the 2.0 branch. I do have Aptana installed as a plugin but the default editor is set to PDT so shouldn't be intefering.

Whenever I type "if", "swi", then ctrl+space for auto complete it shows what is in the image above. The annoying thing is it should just insert the template as soon as you press ctrl+space but instead it shows this menu with a useless entry above the actual template I want to use, so not only does it not auto-complete I have to manually click on the correct template, this happens on all the standard templates.

Any ideas would be appreciated.
