Launch GUI from terminal

I just installed Ubuntu 12.10 x64 onto an unused laptop and reconfigured GRUB to launch to a terminal instead of the GUI as I quite often just want to run some commands without all the other stuff loading and slowing me down.
When I decide I want to launch the GUI (I've changed to Cinnamon by the way) I type STARTX and the GUI launches, but it is missing the taskbar/menu at the bottom of the screen. I can right click and select different items, but am hoping someone has an idea as to why the GUI doesn't launch properly.
If I reconfigure GRUB to boot straight to GUI then it launches properly, so I am fairly sure that it is all configured appropriately.
Thanks for any suggestions anyone has.
