That makes sense. It'd be nice to be able to get rid of it, but I understand that it's not really the highest of priorities when it comes to various improvements and changes to this program. I'd be lying if I said there weren't other changes/improvements I'd want more, haha.

Wow, that was it apparently! I changed the "#" symbols to "@", closed CC3+, and reopened it a couple moments later, and hey presto - there's my symbol catalog, auto-loaded like it should be. So thanks!

I assume I can make similar macros in the Map Notes of every map I make so the correct catalog is always auto-loaded, which is a big time-saver. I hadn't realized that there'd been any kind of "syntax" change at some point with these macros (# vs @), but it's good to know that sometime so simple was the problem.

Re: the program crashing immediately when I hit the "show symbols in map" button - could be related? It's something that happens sometimes, but not all the time, when opening a map, and seemed to be more likely to happen if I opened CC3+ from the taskbar icon (and less likely to happen if I opened it by navigating to an FCW file in Windows Explorer and opening CC3+ by simply opening that file). I'll have to see if it happens again on my national map now that the correct symbol catalog loads automatically - as I said it was sporadic, so I'll have to keep an eye on it for a while to see if the problem still occurs.
