My HP scanner does not respond correctly when I set the ImageLeft, ImageTop etc. properties to fix the size of the scanned image?

We have noticed this problem with several different models of HP Scanjet scanners. An additional procedure called SetImageLayout is provided in TwainControlX which allows all four size properties (ImageLeft, ImageTop, ImageRight and ImageBottom) to be set simultaneously. If SetImageLayout is used instead of the individual properties, everything works fine.
