My wife's Apple mouse (single button - wired - white) is double clicking even when she, or I, single click. I've tried changing settins/speed in Prefs to no avail. It seems to register a second click on release sometimes (more often than not). What do you think would be an economical replacement? I'd like to get her a comfortable, two-button w/scroll wheel mouse - wired. She wouldn't tolerate battery recharging/replacement.<br><br>She might like this one<br><br>
