Hi,
I am having the same issue here.
Smartdraw 2010 - MS Office 2010 but under windows Vista.
Updated even to the latest version of Smartdraw 2010.07. Maybe it is related to the update process, since it worked fine until a few weeks ago.
The symptoms are the same; Push button for export MS Word / Excel - blank, even in an existing MS Word document. However it works for MS Powerpoint.
Any help is welcome.
Kind regards,
Pieter.
