Navigation types

When I decided to make a panorama with Javascript I wasn't sure how to make the navigation. Is it better to just move the panorama left when the mouse cursor is at the left side (and, of course same for the right side:). Or make left/right arrow buttons and move the panorama when the user clicks on them?

Here is another option. Click on the panorama, move it left or right and then release the button. The panorama will continue scrolling in the same direction. I know it isn't perfect (there are problems in Internet explorer), but...



My question is; do you like this way to navigate the panorama? Or - do you like the way it is now?
