First of all, something I should have done from the start: Set the middle ultranav button to "neither" scrolling or magnification. I didn't know that "neither" meant regular middle mouse button until I went into IBM's ultranav wizard. Silly me
Second, I updated the ultranav driver to the latest generic Synaptics drivers. The driver version is 7.12.7.0 and it doesn't seem to conflict or replace any of the IBM-specific elements in the software.
After 3-4 days, still no stuck white pixels. Fingers remain crossed!
