I've completed an installation on my PC to make it a dual-boot system. When I first logged into FC5, Gnome came up. I immediately noticed that I could not see the mouse pointer. The system did recognize mouse movement and clicks, as I blindy tried to click on the right icon or menu option. My PC is a new emachines T6532. It has a Microsoft wheel mouse and the graphics card is an Nvidia Force 6100. During the FC5 installation process, I don't remember anything about configuring the mouse, but it didn't seem an issue, as the mouse pointer was visible at that time.
Secondly, from the state of the Sessions menu, it appeared that KDE was not installed. I'm surprised, as I chose all 3 of the "type of user options" when installing. When I tried to add KDE, Package Manager fails with an error box stating "Unable to retrieve software information" and shuts down when the box is closed. Since this is a completely fresh install, I haven't even had a chance to foul anything up

, so I would appreciate any suggestions as to fixing these two problems.
