Try right-clicking on the journal and open up your Window Settings. Make sure all your sliders are all the way to the right and that "Frame and Titlebar" (or is it "Frame and Title"?) is selected in the drop-down menu. Basically, make sure everything is "turned on," and make sure to click "OK" when you're done.
If everything's already "on," try clicking "Default Opacities" once or twice. That will make sure none of the settings from the journal window you used to use (default or otherwise) are "stuck."
I put my Settings and Close buttons in a similar location in my mods, and this is one of the more common problems people run across.
