>How hard is a FoxExpress application to distribute and to issue new versions of the application I develop?

FoxExpress is simply a framwork for VFP, so you still have a VFP project. The ease or difficulty of deployment will be the same with FoxExpress as for a regular VFP project. It all depends upon the various ActiveX contols and other files used in the app that might need to be installed on workstations.

Having said that, it is common practice amoung VFE developers (and many VFP developers) to build self-updating and even self-installing apps (from maybe a network login script). It's also generally considered a good idea for performance to have much of an application reside on the individual workstations (with VFE or vanilla VFP). There are plenty of good examples around of methods to have the local installs self-update themselves from a network copy.
