The appearance of the User Interface tab in Linux primary OS:

User interface preferences can be different for each user of your computer.
Look and feel:
- Dialog font option is only available in Linux primary OSes. It allows user to select preferable font, its size and other parameters to be used in system dialogs. Click Browse button near the field and choose new font if you wish to. To restore the default font and its size use the Default font button.
- Show tooltips option is only available in Linux primary OSes. It controls the appearance of tooltips for the toolbar buttons and the command buttons on the property page (see Property Page). By default this option is selected.
- Allow to change guest resolution in fullscreen mode. If this option is selected, a virtual machine switched to fullscreen mode tries to change its screen resolution to the host screen resolution. This can be done when the video driver from Parallels Tools is installed in your guest OS.
- Allow to change host resolution in fullscreen mode. If this option is selected, resolution of your host monitor is changed to the resolution of the guest OS when a virtual machine is switched to fullscreen mode. Note that this option has lower priority than the previous one, so if both are selected this option is active only when the Allow to change guest resolution in fullscreen mode option can not be applied.
Help browser:
Note. This option group is only available in Linux primary OSes.
- Help Browser Executable field shows the path to an executable file of web browser used for displaying help for Parallels Workstation. By default help is displayed in Mozilla web browser. If it is not installed on your computer or you prefer another browser, locate its executable file using browse button.
