Blender won't select the object I want to select For some reason I can't seem to select a sword that I duplicated from a previous one. The previous sword is still selectable but the duplicated one is not. For some reason blender selects whatever is behind the object. However I dragged a box over it about 20 times and found that it worked once, but it selected everything with it.
Check to see if it is listed in the Outliner. If it is, click on it's entry. If it still won't highlight, check to see if the arrow icon is toggled. Click it to make sure it's not greyed out. This indicates whether an item is selectable.
