Dreamweaver Web Developers,

This issue has puzzled me for several months but I solved
it today. I am posting it here so if anyone is ready to
pull their hair out like I was, they may stumble on this
documented fix (that is nowhere else on the Net).

I have a few simple small (less than 1k each) rollover
images on a very basic page. I'm using Dreamweaver 4.0 with
its built-in scripts for swapping images on mouseover and
mouseout. Everything seemed to work fine, but the speed of
image swapping in IE for Windows was so sluggish!

IE for Mac worked great, Netscape looked fine. Both of these
took a fraction of a second the first time I moused over to
load them into cache, then when I ran across them back and
forth the swapping was very smooth. But not on IE.

I was pretty convinced that it was a caching issue, because
I noticed a site in australia that has the same script, same
problem. And the delay in the swapping was a little longer.
But there was a delay in the swapping even when I tested my
pages from my own hard drive.I tried deleting my browser
cache, but that wasn't it.

Finally, today, I noticed that I had set my browser to
'Check for newer versions of stored pages - Every visit to
the page' under the settings in the Temporary Internet Files
section of the Internet Options. I had done that so my pages
would refresh as I made incremental changes to them when
working on them. However, that setting does one thing more.
It causes the browser to reload the swap image every time I
mouse over. Hence the delay.

Hope this helps someone someday before they reach the level
of frustration I felt.
