[Fedora-xen] CURSOR STUCK ALONG THE Y

I'm currently attempting to running the Fedora 7 XEN kernel on a Dell 390. Specs: Intel Core 2 Duo E6600 2.40GHz/1066MHz/4MB L2/Dual-core/VT. 128MB PCIe x16 nVidia Quadro NVS 285 Graphics 2GB, 667MHz, DDR2 SDRAM Memory 80GB SATA 3.0Gb/s with NCQ and 8MB DataBurst Cache Problem: Whenever launching the virtual machine (virt-manager) the cursor gets stuck on along the Y-axis. I can freely move along the Y-axis but moving along the X-axis is almost impossible. If I slowly move the mouse it sometimes works, but normally I just get frustrated and reboot the box. Is there a configuration issue I've missed or is this a bug?
