B7377/8 NG ILS APP MODE DOESN´T WORK PROPERLY WITH ONE ENGINE OUT

I´ve been making some tests ina simulation center , and I´ve found out that when I had both engines working ,I had no trouble engaging the app mode in MCP , but making the the same aproach with one engine out, the app mode didn´t arm , unless I had already captured the glideslope. Before somebody says this is normal, in the NGS there is no need of arming VORLOC and then the APP mode, you just press APP and that´s all . So, there is something wrong with PM or CPFlight MCP.

Sorry folks, People found out error in a Sioc Routine , nothing to do with PM ou CPflight. Problem solved.
