I have Fedora 19 running Gnome 3 Shell installed on my laptop, and in a virtual machine running inside VMWare Player on my desktop. The VM has the proprietary VMWare tools and is up to date as of today.
On the laptop I am used to opening the menu by "poking" the corner with the mouse. However I am unable to be able to get it to work in the VM.
I have tried putting the VM to fullscreen and also installing an extension to Gnome that allowed me to configure things like the hot corner threshold. However they did not seem to have any kind of effect.
Is there something in the fact that I run it inside a VM that keeps me from being able to use the hot corner?
