that definition seems to jive with what I said. No radical change in the government was established to give the western countries what we have; in fact, we've taken them for granted essentially since our constitutions/Bill of rights were written; but they did constitute a change in the way of thinking as far as human rights were concerned, so I guess it would fall under that.
But I do know what you mean, and your right; so there is no need for us to get pedantic.
On to the mouse, however;
Now, it's been suggested to try another mouse if possible. This isn't to say you would switch and use that mouse; if it works, however, it will eliminate software issues, mostly meaning the mouse is fubar.
Now, once we can eliminate the mouse itself as the problem(IE, problem exists with backup known good mouse), we can attempt to determine what settings have been changed that are causing this behaviour.
Any Mouse-driver programs, such as Intellipoint, running?
Sounds like you've already inspected the mouse control panel dialog, so I assume you found nothing amiss.
There is one thing that could be causing it; I had a similar issue with a mouse that refused to click at all. The solution was to open it up and clean out the innards. Now it works like new! similar problems with my gamepads and the like were solved in a similar manner.
Only thing is; I've never had a Click-double scenario as you have here- my thinking says it's possible that there is just enough crud in there so that the button barely pushes the click-button underneath- possibly causing two clicks to be detected.
Lastly; I apologize for helping to hijack your thread. the discussion was not leading in a direction that would solve your problem, and I facilitated that.
