[QUOTE="Randy B. Singer, post: 1804976, member: 190607"] Steve, anomalies where the cursor gets momentarily stuck, and/or where keystrokes give unusual results, especially where you have BOTH happening, is usually a sign that there is either a lot of odd processing going on in the background slowing things down in fits and starts, OR that something in your system is being accessed, but that access is unreliable and intermittent. You would troubleshoot it almost exactly as you would a persistent rotating beachball or a nasty slowdown. I have two Web pages that will allow you to do that: Macintosh Beachballs [url=http://www.macattorney.com/rbb.html]Macintosh OS X Beachballs![/url] Macintosh Slowdown Solutions [url=http://www.macattorney.com/sd.html]Macintosh OS X Slowdown Solutions[/url] I can usually guess what the likely culprit will be, but in this case I'm not sure. I'd first try booting from a known good clone backup to rule out a corrupted OS or a system conflict. But I wouldn't be surprised if the problem turns out to be bad RAM or a failing hard drive. Both can be easily tested for. Good luck. [/QUOTE]
