Well, I may be losing my mind, but ... The entries in my To Do List all blink on and off at varying intervals. I had never seen this prior to this morning. They will vanish for about a second, then return for awhile (maybe 10 seconds or so, maybe longer). This is a Series 2 540 model stand alone which has worked perfectly since I got it a couple of years ago. I pulled the plug, waited about a minute, then powered back up. I thought this had fixed it, but a quick check shows it is happening again. Is this a sign of impending drive failure or something else? Or am I just losing it? I have been looking for an excuse to get the new HD but don't want to lose the programs I have not had a chance to watch yet.
