Graphics, Figures & Tables ⇒ longtable- extra page

[rms502]

Hey,
I'm trying to make a table which is quite wide and long. I think it would look best in landscape so I used:
\begin{landscape}
\begin{longtable}{ |l| l| l| l| l|l|p{2.7cm}|p{2.7cm}|p{3cm}|p{2.7cm}|p{2.7cm}|}

content

\caption{blah blah}
\end{longtable}
\end{lanscape}
The table itself looks ok. The trouble is after the table and caption is finished there is an extra landscape page with nothing on it and I'm not sure how to get rid of it!
Any help would be greatly appreciated
