dropdown menu - extra pixels

Hello all,
 i created a pretty simple dropdown menu in Fireworks.  When i export the html 
and slices, i notice that Fireworks puts an extra 1 pixel high row (spacer.gif)

across my entire menu (1 spacer for each button)

 Also, Fireworks includes a 1 pixel column on the right end of the images.

 I have checked all my image sizes and my canvas size and i can't understand 
why this is happening.

 Any help would be appreciated.

 Thank you very much!
 Steve

OK - i found the answer:

 When you export the menu to html code there is an options button.

 Under that options button there is a table tab which has a choice of
"space 
with".  I had chosen (or maybe Fireworks defaults to?) "1-pixel
transparent 
spacer"

 When i changed the choice to "single table - no spacers" the spacers

disappeared - problem solved.
