Righ-click mouse button

So apparently, my sister got a hold of my computer and she used it to work on some report.

But now in order for me to access the right-click menu, I have to double-click. I'm slow when it comes to computers and all of its jargon, so is there any way I could change it back so that I only need to click once?

(It's a pain when copying and pasting(yes I know of ctrl, I just don't use it much))

This was found after a google search so I can't take credit but hey, I care.

From Control Panel> Mouse, check settings. Make sure that right button is
set for right-click.

Edit: I tried it myself, and for Windows Vista it looks like you instead have to switch it between right and left handed. Obviously, make sure it's on right handed.

Thanks for helping out.

But guess what happened? It turned out that Firefox crashed, so that's why I was having trouble right-clicking. Also, the backspace was backing up rather slow. When I cloed the window to see if it was the browser, it was. It told me that it crashed.

Alright, I went through the Control Panel and the mouse is set to default, so it wasn't that. But I did see what my sister altered. She altered the double-click speed along with the keyboard settings.

So I set it back to default, and from there I tweaked it to my preferences! So thanks for the help!

Wierd...

Well, I'm glad it was resolved.
