accessing widgets

Hi, I’m still having trouble with removing and changing a social icon widget. Here’s the situation:

When I open my Appearance page, I see a page titled Widgets on the left. Under it says, Available Widgets and there is a list (archives, calendar, etc.). On the right it reads: sidebar with a small arrow pointing up. Under that is search, Recent posts, Recent Comments, and YASIP Social Icons. If I click in any of those boxes or on any of those arrows, nothing happens. There is no dropdown menu.

Thank you for any help you can provide.
