Below is a revised folder-level JavaScript that works at my end with 
AR8.1.3, when there is more than one opened document . It uses two delayed 
calls to overcome whatever internal problems AR is suffering from. I've 
tried to reduce it to just the one TimeOut, but I can't get it to work. 
I will have another go tomorrow to see if I can come up with a more 
elegant workaround.

var myCurrentDoc;
var myCurrentDocPath;
var myCurrentDocView;

function MyReloadStep1() {
  myCurrentDocView = myCurrentDoc.viewState;
  myCurrentDocPath = myCurrentDoc.path;
  myCurrentDoc.closeDoc();
  app.setTimeOut("MyReloadStep2()",1);
}

MyReloadStep2 = app.trustedFunction(function() {
  app.beginPriv();
      var oDoc = app.openDoc(myCurrentDocPath);
      oDoc.viewState = myCurrentDocView;
  app.endPriv();
});


reloadCurrentDoc = app.trustedFunction(function(currentDoc) {
  app.beginPriv();
     myCurrentDoc = currentDoc;
     app.setTimeOut("MyReloadStep1()",1);
  app.endPriv();
});

app.addMenuItem({
  cName:   "reloadCurrentDoc",
  cUser:   "Reload",
  cParent: "File",
  cExec:   "reloadCurrentDoc(event.target);",
  cEnable: "event.rc = (event.target != null);",
  nPos:    0
});

var oReloadButton = {
  cName: "Reload",
  cExec: "reloadCurrentDoc(event.target);",
  cEnable: "event.rc = (event.target != null);",
  cTooltext: "Reload Current PDF",
  nPos: -1,
  cLabel: "Reload"
};
app.addToolButton(oReloadButton);
