Just a guess: Perhaps you have to increase the video memory setting: Start Virtual Box Manager Select the VM Press Settings Go to Display, tab screen Video memory setting slider You can approximate the setting by multiplying : color depth in bytes * height in pixels * width in pixels Add a few Megabytes to the result and use that setting. Hope this helps. -- Regards, Kees Nuyt ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ VBox-users-community mailing list VBox-users-community@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/vbox-users-community _______________________________________________ Unsubscribe: mailto:vbox-users-community-requ...@lists.sourceforge.net?subject=unsubscribe
