Virtualbox error ------ & gt; solution for abnormal mouse removal on VirtualBox Virtual Machine

Virtualbox error ------> the solution for abnormal mouse usage on the VirtualBox virtual machine is under the Virtualbox virtual machine, and suddenly the mouse usage is abnormal. Two mouse clicks are displayed, one is under the Ubuntu host, and the other is Windows 7. However, Windows 7 cannot be seen, but a response is displayed when you click the left and right buttons, it is a bunch of bugs. Finally, I found the problem: it was caused by the exclusive mouse mode of VirtualBox. After the Enhancement Tool is installed, the mouse in the VM and the mouse in the host can be seamlessly switched, but this also leads to problems in virtual machines. Solution: press the Host + I key to switch to the exclusive mouse mode. My problem is solved. The Host key is usually the ctrl key on the right.
