Chrome, IMCE and Drupal

I'm trying to use the IMCE module for Drupal with CKEditor and when I hit the OK button in IMCE, it generates a JavaScript error from ckeditor.js (3.5.2)

Uncaught TypeError: Cannot call method 'moveToPosition' of undefined
ckeditor.js:86

There's a related ticket over at Drupal for this issue, too:

I'm using:
CKEditor 3.5.2
Drupal Pressflow 6.20.97
IMCE 6.x-2.1
Chrome 12.0.712.0 dev

It works fine in Firefox.

Thanks!
