I have VirtualBox 5.1.6 Installed on Mac OS Sierra, And I have CentOS 7 1511 like Guest, and I'm using KDE Environment Desktop.

Running the Virtual Machine, the Mouse works perfectly. But Sometimes, later of time working with The Mouse and interacting with it, the mouse is not responding to click Events. But I can see it.

2) How Can I to Check the Events (where is located log) related to this issue?
