ddcBar I/O-Tab Scan Suddenly Stops Working

Recently a number of user reported a condition where the Point Editor I/O-Tab Scan utility stops working. Although I have not been able to replicate this condition it has been discovered that a Visio Repair or in some cases a full reinstall of Visio will fix the issue. The problem looks to be caused by updates to Office products that may unintentionally changing some Windows registry entries that effect Visio. If you have this issue please run the Visio Repair in the Programs and Features. If that does not fix the issue try a full reinstall. These steps should restore the needed Visio settings.
