object detection soley for IE4

[webaster]

When using this object detection in javascript

if (document.all &&!document.getElementbyId) {

your javascript here
}

Does this mean only IE4x browsers are targeted

because IE4.x support document.all and NOT
document.getElementbyId

[webaster]

if (document.all &&!document.getElementbyId) {

// whitespace added between && AND!document.getElementbyId
