First off let me say I am using IE7 and version 2008.3 1125
I am currently working on a project with a lot of thumnails. Currently, live, we are using the RadWidnow to popup the full image into a modal window. We really would like to use a mouseover with the Radtooltip (using tooltipmanager), but are running into one major drawback. We want the tooltip to wrap the image perfectly so there is no scrollbars or empty space. If we do not set the Height/Width of the tooltip manager this works great, except that it appears the tooltip no longer can sense the screen boundaries. Images that anywhere near the top, bottom, left, or right will simply overflow off the screen. You see this same result in the following demo:
Just scroll down the page a little and hover over a product....it goes right through the top of the screen. If you set the Height and Width property then the tooltip stays within the page but then you must live with either the scrollbars or empty white space since not all the images are the same deminisions.
