How to enlarge canvas

[ksbigfoot]

I drew an image in Illustrator 10.
When I move my mouse over the image a square shows up, it seems like the right side and bottom are not within the square.
When I save the image for Web, the right and bottom side are cropped off.

Does anyone know how I can fix this?
Thanks

Maybe its something to do with page tiling?

I went to File - Document Setup.
Under Artboard I have Single Full Page selected.
I selected the view to 'Fit on Screen'. It is much smaller than the page and it is not even close to the gutters.
Not sure what is happening.

I found out the answer.
It was crop marks that I seen on the page, I didn't know what they were called.
To get rid of the crop marks I did the following:
Object > Crop Marks > Release
