Apologies if this exists under another guise.

This is just a test site as its simple.
I have seen this on amazon and others though.
It does not seem to affect the operation, but is misleading to a user.
Here is a log fragment taken from in the middle of data entry through hitting the button. The error warning may or may not be significant, so I left it in.

Firefox does not do this, it just says button.

Latest snapshot used, but this has been around for a long time.

Can you please provide exact steps to get to that button? I don't see any Align center button when I go to that page. Also, do you have images disabled?

You are in input field. Enter anything then tab.
Then you are on the button concerned here.

Yes pictures are off.
Turning them on does stop it saying unavailable but otherwise I see no difference as far as things are concerned. I tend to have images off as it can slow some complex web sites down quite a bit.

I never thought to look at the settings in this part of IE, how does this affect it?
Maybe a note in the user guide if this is an issue that is not correctable.

Firefox , I notice says submit query, so this must be reading some other data, and the effect still does not happen even with images off in firefox.

Sorry. I thought align center was the name of the button; I neglected to take into account that you might have reporting of alignment enabled. :)

This is an image button. IE reports unavailable for all images whenever images are disabled. I agree it's a bit silly for image buttons, but I'm not sure we can work around it.

So does the unavailable that is spoken apply to all graphic objects that have obviously not been rendered? Is there no way that those identified as part of a button can be announced in some other way if they need to be?

This obviously does not occur in Firefox.

Maybe unavailable could be replaced when applied to graphics with images off.
