>>When the project manager compiles and exe, it seems to run through all the modules. Then it builds an app and then an exe. Why can it not only process the last file I changed, update the app / exe with that change? Anyone know exactly what it's doing to create the app and then the exe?

>It goes through all of them but for most of them it doesn't really recompile unless you tell it to (checkbox in the dialog or RECOMP keyword). On slower machines... ahem, 15 years ago, you could see the difference in the speed.

Time stamps of files can make a difference too - I ran into this when working across time zones. For example. a .prg won't recompile if the timestamp of the .fxp is later than the .prg file....depending upon what checkboxes and such you select of course. I got stuck on this once for like 2 hours many years ago -- kept recompiling and running but my changes not there in EXE.....uggg lol.
