With 800/900 install mouse problems on overhead panel

I installed the 800/900 over the weekend and since then have not been able to get the mouse working on the overhead panel in both 2D and VC. I tried checking if the 600/700 were still working, but there too, the mouse no longer works in the overhead panel, since the 800/900 installation.Any suggestions to troubleshoot this?Thanks,RichardSystem spec :Win XP, FS2004 UK version, Intel 3.2 GHz, MSI 865PE Neo 2 FIS2R, ATI 9800 Pro, Corsair TwinX DDR500 1GB RAM, WD36GB 10000rpm RAID 0 setup, Audigy 2 ZS sound
