There appears to be a problem with the Resource Module 2007012001 and Moodle 1.7.1+. I've installed this module over my Moodle installation recently and found that I can no longer edit courses because all the topics and the right hand bar dissapears when I click "Edit Course". Reverting back to an older Resource module fixes this problem. Please can anyone help with a working version of the resource module as my moodle is now complaining about not being able to downgrade. Thanks.
See my other post at: http://moodle.org/mod/forum/discuss.php?d=66464#299329 to see how I got to this.
