Trackball losing its magnetic Marbles

... I have had this marble mouse for over a year and never had an issue till a few days ago. It seems to have worked itself out now. I rebooted about 3 hours ago and the problem has not come back yet. it used to reappear about 30-60 min after a reboot so I don't know what to think. It was a very odd problem.
According to some of Tesla's theories regarding electromagnetic disturbances, the cursor behavior you describe could very well be explained by physical science.
I'd be interested to know if you are using a CRT monitor (like a TV), of if you have this problem of the cursor disappearing on an LCD. Also, whether the incidents are more common during the day or at night. Marking down the time, date, duration and time period since startup or reboot would be helpful.
According to Tesla, such occurances are more common above the 42nd parallel (in declination of latitude from the equator), closer to either the North or South poles. While it would be difficult for laymen like us to determine if there is any unusual solar activity (sun spots, solar wind, or solar flares) directly affecting you, the presence of electromagnetically charged particles in the atmosphere can sometimes be visually identified in the night sky as either the the aurora borealis (north) or aurora australis (south), which could help confirm the state of atmospheric condition.
Note: the 2 attached images may help visualize the phenomenom
So, if it happens again, please make a note of the data as described above, and then if it is night time, observe the sky outside to verify the atmospheric conditions around you. Do not venture outside during sunlight hours since the amount of gamma radiation resulting from a solar flare may be harmful over long durations; this is not true at night.
If you can document at least 3 separate incidents, you may be able to demonstrate that this has affected your CRT in a way that has pushed the electron beam into a corner of the screen, such as a lower corner.
This is only a theory, but careful notes on your part could be very helpful in resolving this issue. As you have said, the situation is a bit odd, but the science behind it is sound.
Also, unless you have a grounded electrical plug (3 way) for your monitor, reversing its polarity will either move the "dead spot" on your screen to another corner, or may resolve it all together. Please let us know what happens.
