I'm running xfce4-terminal 0.6.3 and xfce 4.10 on Fedora 20 as a guest in VirtualBox 4.3.12r93733 running on Windows 7.
When I put the scroll bar on the right, the terminal window doesn't have a left border. When I put the scroll bar on the left, there's no right border. And when I disable the scroll bar, the window has no vertical borders at all. Without vertical borders, overlapping terminal windows are awkward.
I've looked at menu options and config files, but I haven't found anything that helps.
Clearly, I'm missing something.
Does anyone have any suggestions?
Have you tried changing the Window Manager theme (Settings Manager >> Window Manager >> Style)? Does it make a difference?
Do you have the virtualbox guest additions installed?
Changing the Window Manager theme to almost anything besides "Default" did the trick.
