EndNote Web Search Fails First Time Used in Session

Whenever I begin an EndNote Web session and attempt a Search of my database using the Search window (to the left of the reference list), the search fails, returning me to the full list of references.  If I reissue the search, it then functions properly for this and all subsequent searches.  Is this a known quirk, and is there a solution?

Hello again.  I am still having this problem.  Do others experience the same thing?  If so, is there a solution?  Thx.
