When you build your project, is the "Rebuild all" option checked?

>In my home directory, I have 9 projects. When I want to rebuild them all, I do a "do BuildApp.prg" which simply rebuild all my 9 projetcs from scratch. 8 apps and 1 exe.
>
>I say from "scratch" because I've made copies ot the projects when the projects contained only the reference to the main program of the app, and stored the copy in a subdir named "projets".
>
>Doing that way when I rebuild, I'm sure not to keep old stuff.

>It works fine and compile all of my 9 projets in a minute or so on a PII 350.

>Every time the project named "liberat.pjx" gets compiled the date and time of a screen named "liberat.scx" gets updated.
>
>The project "liberat.pjx" contains a reference to the program "liberat.prg" which contains a reference to the screen "liberat.scx" with a command "external screen liberat".

>I thought that it's because of the same name used, but I have another project who has the same setup. i.e. grief.pjx refers to grief.prg who refers to grief.scx.
