User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.14) Gecko/20080418 Ubuntu/7.10 (gutsy) Firefox/2.0.0.14
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.14) Gecko/20080418 Ubuntu/7.10 (gutsy) Firefox/2.0.0.14

Used style z-index to position tiny graphic created using <canvas>
underneath transparent button.
Button text is visible and graphic appears beneath button
BUT mouse cursor changes shape as passed over canvas
and mouse clicks not passed to javascript onclick handler.
On part of button not over canvas, clicks are passed to javascript function
as expected.

Change of mouse cursor, suggests problem is buried deep inside browser:-(
Suggests stacking order that is being used is based on the order in
which the button and canvas are drawn and zIndex is being ignored

Reproducible: Always
