As the title suggests, the scrollbars in my desktop seem to have an inconsistent theme. This is apparent in the attached screenshot. The terminal window on the right has a different scrollbar than the Firefox window on the left. Though I have illustrated the problem with Firefox, it is not the only application that suffers from this.
I would like all of my windows to have a scrollbar like the one my terminal has. Have any of you encountered this behavior before? What is causing this? Is there a way to fix it?
Potentially Relevant System Information:
I'm running Fedora 16 and have both Gnome 3 and Xfce installed.
Thank you in advance for any assistance you can provide.
