Jim, without doing any experimenting, it looks to me like the event may no
longer exist when your timeout eventually fires. You might try saving it in
a local variable (with a closure) like this to see if it makes any
difference:
qx.event.message.Bus.subscribe('transport-update',
function(message){
var data = message.getData();
window.setTimeout(function(x){
alert(data)
},0)
}
)
