>thank you for your proposal. Just a few minutes ago I found the solution and it so easy: This obviously is exactly the situation, for which the "Debug info" checkbox is provided for and why it bloats up the build .app and .exe so heavily (see Kilo-Fox, Chapter 14.3 for more detailed information, where I found this hit, which caused me thinking again). If the "Debug info" checkbox is checked, the Build method of the Project Manager includes the missing source. I have had it unchecked all the time, because of its bloating habit.

I knew I'd miss something obvious :)

Actually you could have a project hook class which would turn debug info on or off, depending on some setting, which you could put in place before building... something like

* build.prg
n=messagebox("Include debug info", FlagsForYesNo)
addproperty(_screen, "IncludeDebugInfo", n=6)
build exe myexe from mypjx

And the project hook class would include or remove the debug info depending on the value of _screen.IncludeDebugInfo.
