I apologize in advance if this is an inappropriate place to post this question.I've installed VirtualBox 4.1.26 in Windows 8 6.2 (I don't think I have Pro) and got CentOS 6.4 installed with Guest Additions.  When I enter fullscreen mode, I can still move the cursor around the guest screen, but no clicks are registered.  Works normally when I exit fullscreen.    Anyone point me in the right direction to correct this (or tell me where I should be posting this)?
CentOS 6.4 as VirtualBox guest under Windows 8 host, fullscreen mode causes unresponsive cursor

These issues sound related to your problem:Can't get full screen Centos-64 guest - vista 64 hostHelp with virtualboxIn these they're saying that your xorg.conf file should not include any specific display settings for the screen resolution. I would experiment with adding/removing a line like this in my xorg.conf to confirm:Modes   1280x1024 1024x768 800x600Additionally I would double check your setup steps with the ones outlined in this post:VirtualBox Guest Additions on Fedora 18/17, CentOS/RHEL 6.4/5.9general stepsmkdir /media/VirtualBoxGuestAdditionsmount -r /dev/cdrom /media/VirtualBoxGuestAdditionsyum update kernel*rebootyum install gcc kernel-devel kernel-headers dkms make bzip2Then set this variable:## Current running kernel on Fedora, CentOS 6 and Red Hat (RHEL) 6 ##KERN_DIR=/usr/src/kernels/`uname -r`## Export KERN_DIR ##export KERN_DIRInstall guest additions:cd /media/VirtualBoxGuestAdditions# 32-bit and 64-bit systems run following./VBoxLinuxAdditions.run
