I have an Automation Add-In with several UDF's. These get loaded properly and I can use them by either typing in the formula or through the Function Wizard. However, in a cell when I type "=" and the start of one of the function names, it does not find my function in the drop-down Intellisense. At the bottom of a blog post that David Gainer made (http://blogs.msdn.com/excel/archive/2005/10/19/482826.aspx) he is describing the new Intellisense feature and says that it will work for Automation Add-Ins... but it does not appear to. Anyone know how to get it working?
