Im cannot remeber if you can do this with the open source version but there is a set of tools to help with this type of situation. All you need to do is install guest additions. For detailed information check the VBOX user manual on the innotek website. <div class="gmail_quote">On Tue, Mar 4, 2008 at 11:30 AM, Frederik De Richter <<a href="mailto:frederik.de.richter@googlemail.com">frederik.de.richter@googlemail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I'm happily running Ubuntu Heron in a VirtualBox. I could not find out how I can maximize the window within VB. Is there a setting you can change? or is this restricted by the amount of Video Mem (I put it on max: 128 MB -- base Mem : 923 MB). Even if I use Full Screen Mode, the window size is still too small for some programs, so I cannot see some buttons situated at the bottom of the some applications. Hope this makes sense. erik -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> -- Jim Rosser Winchester Designs
