HELP!! Why can't I copy/paste normally?

About an hour ago, I had some programs that wouldn't respond, so I did the Ctrl-Alt-Delete routine, sending about 6 error reports before they would close down, and now when I try to right click to copy/paste something, I get TWO square outlines, and have to run my cursor arrow up and down the list to find the ones I want. It looks like my Start Menu!! For instance, when over just a white area (like below where it mentions the community guidelines), I'd get options like Back,Forward; IM this page to a friend; Email this page to friend; Save Background As; Select All; Create Shortcut; View Source; etc.

In the area where I'm typing and/or would want to copy/paste, I get the options Select All; Delete; Paste; Copy; Cut; and Undo.

Would it help to do a System Restore?? This about the programs not responding just started a month or so ago and now I can set my watch by it (ALWAYS 9-12 midnight), but the copy/paste messup just started tonight.
