Search Window Opens When Clicking On My Pictures/My Videos/My Music

[slaerakuyume]

Whenever I left click (single or double) on the following, trying to get them to open, a search box pops up for me:

My Pictures
My Videos
My Music
My eBooks
My Recieved Files

When I right click on the folder icon instead of left clicking, I can open the folder by going down and clicking 'open'. However, Search is in bold at the top of the drop down menu.

It never has done this before, but I'm guessing I've changed a setting or something... could someone help me figure out how to change it back so when I left click, it opens the folder instead of opening a search box?
