Comments on DOM events portability

The layerX and layerY solutions will break in IE9 when run in an (i)frame.

IE9 pretends to support layerX and layerY but gives wholefully wrong values when run from a document inside an (i)frame. Somehow the offset off this document relative to its parent is added to the total.

Ah. Well, I don’t use such, which is probably why Square Shooter is reported to work in IE9. I seem to remember Firefox having a similar issue until I learned to set the canvas element to Position: relative. Good to know!
