Just noticed something and wanted to bounce this off some folks here. I recently created a VM running in VirtualBox and using Zorin 6, which is a 12.04 based linux distro. It is amazingly similar in presentation to a windows desktop. I am developing this VM for a windows friend, but I am having fun with it too. The host system is Win 7 Pro. I have used a bunch of VMs but I have never seen what this one does. I don't know if its because this distro of 12.04 is so window's like in configuration but I can move the mouse between the host and guest without having to click to change as I normally do with other VM's. Its very easy to go back and forth although when I am running a VM I tend to stay inside it most of the time. Why would my mouse be so free to move around in this configuration? Both the host and guest are clean and run great. The 12.04 VM is "hosting" the TBB and I am concealing as much personal machine hardware id as possible. While its very convenient to have a mouse working this freely, in my mind I am trying to make sure other info cannot pass freely between the host and guest. The configuration and parameters all look solid. Do I have anything to be concerned about regarding strictly this mouse thing?
