Submit By Email Doesn't Launch Outlook 2010 as Default Mail Client, though Outlook is properly set a

[RelKraken950]

A form designed in LiveCycle Designer with a Submit By Email button, doesn't launch Outlook 2010 (Standard Edition) when clicked, although Outlook is properly configured as Default Mail Client.  Checked with Microsoft and followed all proper steps yet the button doesn't invoke Outlook onClick.  However, Outlook is launched if a link or html button, set to the mailto syntax is clicked.  Is this a PDF form issue for LiveCycle or is there something I am missing?  Please any ideas?

I have this problem on Win7 64bit, but it seems to work fine with XP and Vista. Not sure about Win7 32bit.

I've also seen the problem in the past with programs like Thunderbird set to be the default email client (on XP).

I've never been able to figure out if it's an Adobe or Microsoft problem. Adobe uses the MAPI settings to find the email client.
