Next button not visible during install in VirtualBox

[DeathByDenim]

I downloaded the Kubuntu 18.04-beta1 iso and did an install in VirtualBox 5.0.40_Ubuntu r115130. During the install the screen was too small to show the Next button. Resizing the virtualbox window had no effect.

Workaround is to use the Tab button and guess when the Next button is selected.
