search instead of open

ive been trying to change the icons for my folders and such, so i was doing
so under tools>folder options>file types. i changed the "file folder" icon
to the one i want, but now, when ever i click on any folder (when
navigating), it pops up a search window. and when i right click on any
folder, "Search..." is in bold at the very top of the menu. under the
advance tab where i was editing the icons, there is a box for choosing the
action to take and i can set a default, well, none of the actions are
selected for default and there is not an "open" or "explore" action like are
in the action box of the regular "folder" file type.
