Sober, thanks for the advice. I think a lot of my problems have been because of my 32 bit system not having enough available Ram for the modded game to work. That would explain why reloading the game can fix the problems, also why the problems multiply the closer I get to a port.

Since I downloaded the CFF Explorer program, and used it and applied the cmd prompt instruction, I was able to start a late war career (Using Open Horizons II!) without any errors, crashes, or glitches. (I have 4 gb of ram)

Fingers crossed that this solution holds up. Thanks again.

Whatever I have done in this process, including reinstalling all of my mods and applying the .Exe ram tweak with CFF Explorer, the radar does work now, solidly.

Trevally, thanks for your replies. Apparently we were both typing at the same time. As I said above, I think Ram has been the issue. I have had a series of problems running the game with mods--new UIs, Open Horizons II, usually having both of those installed at the same time. My problems have included the sound/navigator/depth-under-keel glitch, myriad CTDs, and recurrent graphical glitches where various textures fail to render, for example a big white blank where the Attack Scope lens should be, or white glowing tiles where my torpedoes and sub systems should be. These problems have disappeared, then recurred without warning. It's been very frustrating.

Ram is the most likely explanation, since it is a variable, and nothing else should be.

So I am hoping the latest steps at least tame the problems, or else I'm gonna have to reinstall SH4 since I cannot afford a new computer, or even a new operating system.

Thanks to all for their explanations and suggestions.
