This is driving me insane... All of a sudden my mouse cursor starts jumping and clicking around by its own. It doesn't look like somebody is remote controlling it. It rather is jumping around randomly, executing clicks or context menu commands just without any obvious aim.
This usually happens while I am working a while with the MacBook sitting on my lap. My feeling is that battery level could play a role here since the problem occurs only when the battery got drained down to below 50%. But it is just an impression. Could also have something to do with temperature, although I do not do CPU heavy stuff (just browsing).
I could do nothing against it. I switched off WLAN and Bluetooth. No fancy touchpad driver is running (though I had one running some time ago, called magicprefs).
There are some similar cases around the web but I did not find any solution yet.
Any help would be WOW, rainer
