Reproducible: Always Steps to Reproduce: 1. Open the Preferences dialog. 2. Switch to a Preferences page with <expander/>s that has a scrollbar in the <vbox/>. 3. Attempt to scroll using the scrollwheel. Actual Results: The content did not scroll. Expected Results: The content should scroll. Any widget in the <vbox/>, such as a <checkbox/>, <button/> or <expander/> is enough to focus the box and make the scrollwheel work. FWIW I believe this is just a focus problem.

Fixed on the trunk, but the patch was too late and too scary for the branch. *** This bug has been marked as a duplicate of 97283 ***
