Outputing to AI file from DRAW ver 9.397

Hi, dear fellows,

I am doing graphic design jobs in Hong Kong.  Corel is not very popular here and I need to convert my works to AI for the printer who uses Photoshop.  The resulting files always contains a square object some where in the middle of the composition and cannot be deleted within Photo Illustrator.  At first, I wonder if this is just a equivalent of paper border in DRAW and I tried to change my original DRAW file with a bigger paper size.  However, the result is the same -- a small square within the graphics.

Anybody experienced such problem before?  This old version of Corel is currently installed in window XP platform.
