I'm using Windows 7 x64 host, just installed Mountain Lion following this guide. Everything goes smoothly with a success. However, every time I've clicked the Launchpad, the whole box got hung for quite a moment, before the pad finally got displayed little by little. It gets even worse if I try to do anything other than just clicking a program to launch it.
Any idea about why? Or better, is there suggestion/solution?
My VirtualBox version is 4.2.0 r80737
BTW, anyone tried updating the box to 10.8.2? Not sure if it'll work after update.
