I have a Dell Precision XPS 7100, 16GB and AMD 6-core processor, I installed VMWorkstation 7.1.6 build-744570, my computer has been running smoothly and I always keep it in optimum conditions, I have installed various Linuxes onto the Workstation, but very often when I run Centos 6.4, if I minimize it, then it hangs up, I have to use Ctrl-Alt-Del to close it and restart the Workstation, the Centos 6.4 is still there (no need to reboot it), but this is very very annoying!
I noticed that someone else post similar message on VMWare website, but no solid response. BTW, I don't see problem with virtual machines running Ubuntu, Win2008, RHEL or SuSE, just Centos 6.4!
