Note that lights ends at the FAR SIDE of objects blocking them, this means that the wall around the lighted area will always be lighted. Generally, this makes for much better visuals otherwise you wouldn't be able to see the walls at all which looks weird, but it results in an undesirable effects when your wall si the entire area outside the path, like typically in caves. The way to fix this is to use a set of thin walls on a dedicated light blocker sheet. I usually draw these slightly inside the cave walls, allowing for the light to illuminate the edge of the cave wall. Note that the lighting is also computed on a raster rendering of the map, which means it needs to deal with pixles. This makes very thin lines unsuitable, as light can shine through gaps, so make sure such blocker lines have a certain amount of thickness.

For the map border, just erase and redraw it. The technical map border is just four lines outlining the map on the MAP BORDER layer.

1. There isn't a catalog filter supplied with this style (may be an oversight from Ralf?). Just use :ICON_CATALOG: to open the catalog if you have closed it. Except for some chimney symbols for use with houses drawn with the house tool, everything is in one single symbol catalog anyway, unless you mix symbols in from other styles, you should just have this one symbol catalog loaded all the time. A quick way to reload the catalog is also just to save the map, then pick the map from the recent map entries in the file menu, as this will reload the map with the CA161 catalog showing.
2. It should certainly be there. Try grabbing a new copy of the SS4 installer to make sure you have the latest one and do a repair install with that.
3. You've already discussed roads with Sue, but just to clarify, the On modifier doesn't try to merge the roads, it just makes sure that the node you place is exactly on the other entity so there won't be any gaps/etc. But depending on things like fill and such, it may still be very visible that it is another entity there. For smaller roads merging with larger roads, it often looks best if you use :CC2BEHIND: to bring the smaller road behind the larger one, or the road that is ending behind the road that continues on.
4. This only works correctly if the house symbols are proper CD3 style symbols. They require some extra entities for CC3+ to be able to figure out the floorplan. If the symbols doesn't have this information, it defaults to just including the symbol itself so you at least have some kind of guide to use to manually trace the walls to get the right size and shape. Unfortunately, it looks like the CA161 symbols are NOT proper CD3 style symbols.

Welcome.

You can click the :TOOLSICON: button to change the toolbar button sizes.

Don't hesitate to post if you have any questions.

There are three entities in your map that is causing problems. Not sure how they occurred, but if you erase them, the zooming problem should go away.

These are entity numbers 114189, 114190, 115004

To erase an entity by it,s number, click :CC2ERASE: then right click inside the drawing area and from the selection pop-up, select more -> Entity Tag #. The command prompt should then show a Tag #: prompt. Type in one of the entity numbers from my list above and hit enter. If you did this correctly, the command prompt should show that you have one entity selected. Now, right click again and select Do It. Repeat for the remaining two entity numbers.

Note that there isn't a single default scale for symbol that will work for both these sets of symbols, as these are not scaled in relation to each other. When mixing two different types of maps like this, you'll basically have to do a little work and experiment a bit with what scale works for the city symbols and for the overland symbols individually, and make a note of these two scales (hint: store it in a map note so it follows the map).
