Problem: White line across top of presentation... how do I remove

[I_am_a_clown]

A 1 pixel white line has appeared across the top of a presentation in preview
and in a powerpoint show. The original graphic does not have the 1 pixel
line, yet when imported into the presentation, the line appears.

Any suggesteions for what it might be or how I might remove it?

The page has been set up to a custom size in centimetres that matches 1280 x
854 pixels, which is the pixel resolution of the destination device, a 15.4"
widescreen laptop.

Your feedback would be greatly appreciated....

Since you're importing it in from another slide, it may be an invisible
object on the original slide. In the conversion, it might very well change
color. Try Edit>Select All to see if the line gets selected with everything
else. If it does, then you can delete it.
