I solved the problem--all of them. The Total Overhaul comes comes with a vastly improved PDSC. It's not realistic, but looks good, works a whole lot better than the original (!) and provides lots of useful features, including call outs, and it will even calculate and drive your EPR bugs. There are graphical improvements, including a nice Spotlights profile that includes a red dome light. It works fine in v5.1. This makes the 737 Captain a viable v5 airplane with a lot of issues resolved. As far as the glideslope cue, I did a a manual ILS approach using and the glideslope worked fine. Best of all, it even has a one-click configurable installer. The only trick (and it isn't much of one) is when you point the installer to P3Dv5, you must remove the v4, which will be in the path. Not exactly brain surgery, but it baffled me for a while.
