Ah, yea, you need a newer build of the dll file too.

I've uploaded an updated zip with a new dll file too. Remember to close all instances of CC3+ before replacing it.

I wrote a tool for that: http://cc.monsen.cc/tools/cc3monsentools.html

Yea, that's DELAYDRAWSYM.

That setting is system-specific and not map-specific, so it won't be automatically turned on when people load the map unless is it is added to the map loading macro.

I can't provide a full explanation here, especially since this isn't really something I have really noticed myself.

But let me address one thing at least:

All CC3+ maps have a setting that determine if effects are on or off on load, you'll find this in the :CC2RESMODE: dialog. This is a per map setting. If this is off, the map is loaded with effects off, even if it was turned on inside CC3+ previously. You can override this behavior from Tools -> Options

Now, while you experience that effects randomly turns off, I don't know, but i suspect it could be due to loading a file that sets this value. There are lots of cases where CC3+ loads map files, for example, symbol catalogs are actually just map files with a different extension, and drawing tool previews in the symbol catalog window can also be map files. I am suspecting that maybe the value is incorrectly set when something like this is loaded.

You can just rename it. The maps doesn't refer back to the .fsc file even if you've inserted symbols from it. As long as you don't rename any of the underlying art (png) files, or the folder/path they're in, you're fine.
