Re: Rollovers - images don't preload - why?

Keith, I can't thank you enough for going to the trouble to look for me.

And for all you others who suggested possibilities for me.

The solution turned out to be nothing.  It was indeed my browser that was 
the problem.  I had no idea until you friendly folks told me that selecting 
my IE5's preferences "Check for newer versions of stored pages" to "every 
time" would have the effect of causing it to go and get new copies of the 
rollover images every time the mouse came by.

So in fact my page had been working ok all along, it was only my browser 
that wasn't working how I wanted it.

But Keith also suggested an improvement to my code that made it work faster 
as well.   I have to figure out now how to change my Fireworks so it puts 
the preload images command in the head not the body tags.

Thanks everyone.

Cheers,
