If I open a new window (reference "pop") that contains an iframe with a
PDF in it and then call this code on the window:

var cBtn = pop.document.createElement("p");
cBtn.appendChild( pop.document.createTextNode("close") );

cBtn.style.position = "absolute";
cBtn.style.right = "6px";
cBtn.style.top = "6px";
cBtn.style.margin = "0";
cBtn.style.fontFamily = "Verdana, Arial, Helvetica, sans-serif";
cBtn.style.fontSize = "11px";

cBtn.onmouseout = function(){ this.style.color = "#333333"; };
cBtn.onmouseover = function(){ this.style.color = "#999999"; };
cBtn.onclick = function(){ pop.close(); };

pop.document.body.appendChild(cBtn);

pop.document.body.style.overflow = "hidden"; // --> freezes here

cBtn = null;


"pop" "freezes" 8 times out of 10. If I comment out the line then the
window opens properly and cBtn is added to the window and responds as
expected. If I replace the PDF with a "typical" HTML page the window
opens properly.

Why would setting the overflow cause the window to freeze?

Possibility: The PDF plugin triggered by the iframe cannot deal with cropped
content.
