Mac Forum / General / Networking / November 2006Pull Down Menus Automatically Scrolling/Cursor Jumping Around
Every so often (a few times a year), my Mac (OS 10.3.9) acts strange. The pull down menus in the Finder and any open application automatically scroll from bottom to top (when you click on the pull down menu, the list appears and each item is the list is automatically highlighted for a breif moment, starting at the bottom of the list moving up to the top, then it starts over again at the bottom). If I click and hold the mouse button the scrolling will temporarily stop. As soon as I release the button, the scrolling starts up again. If I am using Safari, it will also automatically "page back" . In the finder, the cursor will jump around the screen erradically. When I restart the system, everything reverts to normal. This would not be a big issue, except that it started doing it all the time now (I just applied the recent iTunes update, not sure if its related or not). Has anyone else experienced this problem? Any fix? I have not been able to find anythin posted anywhere. > Every so often (a few times a year), my Mac (OS 10.3.9) acts strange. > The pull down menus in the Finder and any open application [quoted text clipped - 13 lines] > Has anyone else experienced this problem?

Also, you haven't said which Mac you have. I experienced similar wierd things happening that turned out to be trackpad - mouse interaction on my laptop. I cured them by altering the settings in System Preferences - Keyboard and Mouse to "ignore trackpad when mouse is present".

Then try cleaning the keyboard. Try a different USB keyboard. Try working the suspect keys a few times.

So the stuck key theory cannot explain this phenomenon (it was the first thing I thought of at the time, so I tested, and rejected it). m.

Where have I (we) seen this behaviour before then? Perhaps it differs for OS versions, or a preference setting. I certainly haven't used this feature enough to be sure, but now that I think about it, it would be unexpected behaviour. To the OP: sorry for misdirection, but do check the keyboard viewer and consider the remote possibility of a stuck key related problem, even if the true scenario is more complicated.

Where have I (we) seen this behaviour before then? I was reminded of a behavior where successive items on the Desktop would be selected. That was because of a stuck key. m.
