I am using a clean install of Xubuntu, running as a Guest on windows 7 using virtualbox, and default options for XFCE as the window manager.
For some reason when I maximise any window (or open a application that has a maximised window), the window decorations (title bar, close, minimise and maximise) are permanently lost, even when the window is un-maximised. How do I prevent this from happening?
I have tried changing as many settings as I can find in the System and Display tabs in virtual box that don't give me non-optimal settings (e.g. 3D acceleration), changing the amount of RAM, VRAM, CPU, monitors, re-installing guest additions, updating xubuntu packages, and tweaking the settings in the Window Manager Tweaks. Nothing tried so far seems to fix the issue.
