Flickering mouse pointer when scrolling background images

P: n/a
I have a JavaScript routine that runs on a timer and updates the position of a
background image using the CSS background-position property. In Internet
Explorer, it changes the mouse pointer to an hourglass when it refreshes the
screen, and this is really annoying since it happens on the timer, about every
100 milliseconds or so. Is there anything I can do about this? Thank you
very much.

Every time the os has to spent cpu, RAM, user system resources to
refresh, repaint and redraw a page, the user should be notified and
informed of this (via cursor or progress bar or statusbar). It's even a
security issue. Way too many scripts on the web abuse and
over-excessively abuse the user system resources just to create
content-free bells and whistles pages. Not everyone has a 2.4Ghz Pentium
4 with 512MB RAM with an highly performant graphic card, you see;
browser application running on more modest computer configuration CRASH
when trying to cope with highly demanding user-resources DHTML scripts.
So if you're going to script the background-position, background-image
with a timer, it better be useful, meaningful to the user. Otherwise,
the user should at least be able to turn if off easily.

My 2 cents.
