Hi everyone, I''m having a problem dragging a div with a background image using the draggable library. What happens is that, while I''m dragging it, it reloads the background image with each pixel movement (like an ''onDrag'' function). Has anyone else experienced this, or does anyone know how to fix it? Thanks in advance.

I''ve had a similar problem whenever anything changes requiring the element to be repainted (a new class for a parent element, for example). The precise circumstances escape me, but the root cause is that IE is not caching the image, but requesting it each time it''s needed (once for each list item, for example). I haven''t concerned myself with it, so I don''t know whether it''s due to client-side caching (which I know isn''t working properly in my case), or whether it''s an IE bug, or something else entirely. Try setting your webserver/appserver to make sure the image is caching, then try it again.

Thanks Tom. Looks like it wasn''t caching because I was using a development server...seems to be working now. It still flickers as I drag, but at least it isn''t costing bandwidth.

You need to turn on caching on background images on IE:
try {
document.execCommand("BackgroundImageCache", false, true);
} catch(err) {
// something else :)
}
that stopped my flickering
cheers,
Jani
