Thank you all for your replies. Unfortunately I cannot tell you what had
happened. On the next day the problem evaporated without leaving a chance to
figure out what was the reason for its occurence. I believe that some
settings might have been changed by my co-worker. Anyway, thank you all!

One of my co-workers using the same template for creating documents in Word
2003 as other my co-workers, has recently faced the problem with manually
changing column width in a Word table. When attempting to drag the column
border nothing happens at all. Since the problem can only be reproduced on
that co-worker's PC, I assume that some Word setting might be turned on or
off that prevents manual column resizing. Does anyone know what this might be
and how to solve this?
