style bg image reloaded

[whatifif]

Hi,

I used javascript code, onmouseup and style tag, style="background:#cccccc url(i/image.gif) no-repeat center center" in my web page.

Then, the background image is re-downloaded whenever I mouse-up on any web page so that the image is blinking.

Anybody knows or experienced this problem and also how to prevent this problem ???

I found the reason.

I put this code inside the onMouseUp(), "document.body.style.cursor = "normal";" which caused the image reloaded.
