recompiling projects with errors

I am using the Momemtics 6.2.1 Ide on Windows 2000. I am building a qnx c
application for the x86 architecture, release level only, all other default
settings. When the default .c file
int main(int argc, char *argv[]) {
printf(“Welcome to the Momentics IDE\n”);

I remove the ; from the print statement and ctrl-s this causes a recompile
and the appropriate red x appears in the ide. I now correct the problem
(add the ; back in) when I ctrl-s the file saves but does not recompile. I
make another change (like adding a space) and save and it recompiles fine.
