There are some known issues with ActiveDocs, and their usage is not advocated. In fact, I would recommend that you avoid using ActiveDocs in VFP, they may not even be supported in future versions of VFP. We work very hard for full backward compatibilty, but ActiveDocs may be a special case since they do not offer much security and there are very little business cases for their use. What I would recommend is to use ASP.NET with VFP as a replacement for any application that does or may consider using ActiveDocs.
