Are there any known issues with the Philips SpeechMike III being used within Agfa's TalkStation application?

Yes, as of today (6.1.11), the Philips SpeechMike III will not work within Agfa’s system called TalkStation.  The issue is caused by TalkStation. 

The Philips engineers have contacted the Agfa’s engineers to add the SpeechMike III compatiblity.  At this time, the two will not work together. The TalkStation application will only accept input from the 2nd generation of Philips SpeechMike’s, which have officially been discontinued.
