When opening a new document with a Basic Macro assigned to a push button with
this code

>>Sub Open_Document
>>Dim mArgs(2) as New com.sun.star.beans.PropertyValue
>>Dim oDocument as Object

>>mArgs(0).Name = "ReadOnly"
>>mArgs(0).Value = True

>>mArgs(1).Name = "MacroExecMode"
>>mArgs(1).Value = 4

>>mArgs(2).Name = "AsTemplate"
>>mArgs(2).Value = FALSE 

>>oDocument =
>>ThisComponent.getCurrentController.GetFrame.loadComponentFromURL("The_Filepath","_blank",0,
 mArgs())

>>End Sub


Macros don't work in the newly opened document that has push buttons either. It
makes no difference when using 

- macro:// - URLs or the integrated Macro assigning feature. 
- opening the document as template or not (when opening a Template, macro:// -
assigned buttons get a "no privileges message" although the options security
dialog is set to "always run")
- any of the MacroExecMode modes or not
- _self, _blank or any other frame
- Stardesktop.getCurrentController..... instead of ThisComponent......
- a ThisComponent.reload function when the new document is opened
- the global macro library or the documents library

This also doesn't work in the 1.9 m51 of the Developers Build
