Hi! I am a new user of this feature and tool and would like to transfer data and info to and from Windows Xp in the Virtualbox running on a Linux Ubuntu platform. My first version of Virtualbox was 2._ _ _ which said it did not support that feature. Therefore, I upgraded to 3._ _ _ which supports it but the flash does not show nor appear in the XP window. How do I get to use my flash on both parallel running systems?
