Disable SendNow Option

Hi,

I am using Acrobat X Standard on a Windows 7 64 bit machine. 

Is there a way to disable the SendNow option?  After creating a PDF, I click on the envelope icon and it takes 3-4 seconds for the Send Files bar to open.  I then choose the Attach to Email radio button and it takes 5-6 seconds before the Outlook 2007 new message window appears (Outlook 2007 was already running).

Since I never use the SendNow, I'd like to return to the old functionality of clicking on the envelope icon and getting a near-immediate response of an Outlook new message window appearing.

Thanks!
