Thanks for the help. I think you're correct that it could be a hardware issue. When the computer was still an Windows machine, I didn't notice it since I wasn't doing anything that required me to use the arrow keys like using a spreadsheet. Or it could all be coincidence that it happen at the same time I was trying to configure kpilot to sync my palm. Anyway, I'll try cleaning and looking at other options. Thanks...
