Hi crjebay,
This is not an Auctiva issue.
The screen settings on your desktop and the laptop are different. You would have to go into Control Panel > Display > Settings to see what those settings would be.
The laptop is probably set at 800 X 600. I have my laptop set at 1024 X 768 and seldom run into a listing that has to be scrolled (unless someone has put several pics in a horizontal line).
