Position of Signature Tools Areas

Hi Baowen,

What version are you running? Can you try updating to 7.3.9? This snippet works for me just fine when I click sign in a PDF document:

  instance.setSelectedTab('signatureModal', 'textSignaturePanelButton');
  annotManager.setIsAdminUser(true)
  annotManager.setCurrentUser('unique user');

Is this the behaviour you were expecting?:
sign2

Cheers,
Dustin
