What has changed that will affect your previous PDF-XChange Version 3 code?

The most significant change for developer's regarding coding your application is that we now no longer provide communication to the driver using Escape Codes or Windows Messaging as previously - all communication is now provided via the 32 or 64 bit ActiveX objects provided.
