I can\'t fire personal events using Javascript in IE. In Firefox work great.
My code is:
var evento;
if(document.createEventObject)
{
evento
As I read the relevant MSDN article page on the createEventObject method, it appears as though it isn't used for creating custom event - it is used for creating custom objects that can be passed to already existing events.
Description: Generates an event object to pass event context information when you use the fireEvent method.

Update: You are getting the "invalid arguments" error because 'eventoPersonal' is not an acceptable event to fire.
