**kallol** · 04-16-2007, 06:08 AM

I have a simple HTML page where I have a form with in a <div style="height: 600px; width: 100%; overflow: auto;">. The mentioned div styles are mandatory to get the expected behavior of the div.Now, in Firefox, the page appears properly as expected. I can scroll down and up the div part by dragging the scroll bar by mouse and I can scroll down and up the div part by rolling up and down the mouse wheel as well. But I am facing the problem if I single-click the mouse wheel, the four headed mouse navigation icon appears and not able to scroll the page up and down by simply moving the icon!In other browser I am getting up and down two headed mouse wheel navigation icon and it allows me to scroll the page up and down by simply moving the icon as expected.Please help.

I don't see where is the problem.

The mouse wheel click is sensed bring up this "arrow scroll" behaviour.
It's designed for peoples using laptop or old mouses without scroll button.

As this function is designed to scroll in the page, it won't scroll into elements.
If it's what you want to do, I'm affraid there isn't easy solution to do it.

But can I ask you how this could be a "big accessibility issue" ?
I don't really see why.

If it’s only designed for Laptop user and mouse without scroll button, then mouse with wheel should not have the ability to get navigation arrow headed icon option to do so and its working fine in IE as expected as I described in my post.

And accessibility concern. For a specific application, I have a huge range of power user group who used to do the same way I explained and they are getting problem in FF and expecting the same should work as IE.

It's an option in Firefox.
You can enable or disable it via

tools->options->general->advanced-> use autoScrolling

After that, for a program, a wheel click event is not different thant a middle click event, as it's the same.
All the interpretation of the event is left to the developpers.

Heck, what about those peoples who map middle button click to "close window" ?
It's not something, in my opinion, you can really rely on.
It's too easily modified by extentions, or programs.
