Resizing OLE objects not working or I don't know how to...

I can insert an OLE object in a dwg but can't do much with the size.  I can make some of them bigger but not smaller.  I did manage to make an excel sheet smaller until it went invisible, I had to undo to get it back.  I can't make the Word doc smaller, only bigger. 

Are there any tricks to this or is it a bug? 

thanks
