Aptana won't save editor preferences

I've got a little (big) problem in Aptana. Whenever I try to edit my settings for a specific editor, I click "Apply", then "OK", but my preferences don't get saved, and if I open the settings again, the default ones are shown. What migh开发者_运维问答t be causing the problem?

I'm using Ubuntu 11.04 with Aptana build 3.0.4.201108101506.

I'm looking forward to reading your suggestions.

EDIT: The situations changed with version 3.0.5. Now, YAML editor's preferences get erased when closing the settings window as before, while others editors' ones are overridden with defaults when closing the IDE... This is very strange.

1. open preferences (settings)
2. click General
3. click editors
4. click text editors
5. change displayed tab width to 4
6. check insert spaces for tabs
7. click apply
8. click ok
9. open preferences (settings)
10. click aptana studio
11. click editors
12. click YAML (or desired editor)
13. change tab policy to use spaces
14. change tab size to 4

this worked for me
