Problem with the Height and Width of my scalebar...

HI Philippe,
I suspect that your map's projection and units settings are not complete.
It might be trying its best to make the scalebar, but will look at those
settings to figure it out.  Do you set map units or map projection in your
code or map file?  Post it so we can see.
