You remind me about similar problem in the Project Manager. When you build APP/EXE and an error is encountered during compilation, you can choose to ignore it. After that when you build again, the error will not be shown because PRG is not recompiled. However "Recompile All" options will bring all such errors to surface. The bottom line, be carefull using "Recompile All" on somebody's the projects.

>The line with the error is probably tagged as a line with an error, but since it doesn't execute, it just skips silently over it. Which probably explains why I used to catch compile errors at run time, when I didn't have "compile when saved" on. I actually still don't turn it on - now I have a little prg which compiles an app and runs it, so any compile errors are caught then.
