DocuSign for Salesforce - Partial visualforce page: embedded tagger not properly sized

Issue

When sending via DocuSign for Salesforce, some users get a tagging panel that is unusually short.

Cause

This is a known issue in DocuSign for Salesforce version 6.6.2 and older, and occurs for non-administrative users who are Lightning enabled but sending out of the Classic Salesforce interface.

This issue has been addressed in version 6.7 (available Feb 2017)

Workaround 

If Lightning is not required for the affected user's work, it can be disabled for them:
a) as Salesforce Administrator, select Setup > Lightning Experience
b) scroll down to "Decide Who Can Use Lightning Experience" and click on Select Users
c) find the user, and uncheck user


Alternatively, an account wide option can resolve this:
Navigate to DocuSign Admin > Settings > Check "Display DocuSign tagger page in new window"

If neither of these resolve the issue, please contact DocuSign Support.
