Another thing when it comes to text, make sure to pick a font available on your computer. The first list shown in the Text Properties dialog are fonts defined in your map, and may include a font you don't have (Click 'More fonts' to access the list of fonts on your computer). If you pick a font you don't have, CC3+ will render a replacement font, usually Arial, which could result in no visible change if the font was already rendering using Arial.

Also, you said you used edit properties to check sheet/layer. Be aware that the values listed here are NOT the current properties of the entity picked, but rather the currently set properties (as seen on the status bar) used when creating new entities. Change Properties/Edit Properties is not a way of checking an entity, you need to use List as Jim said to do that.

The terrain tools for this map doesn't use symbol fill, but rather hatch styles. These have a fixed scale. This is discussed on page 2 for the mapping guide for that annual issue.

The only way of changing scale for these fills is either scaling things after they have been drawn (not very practical when you try to make the area fit something) or by editing the hatch style fills themselves. These are regular CC3+ drawings, and lives in the @Hatch Styles folder. Obviously, you shouldn't edit the originals, but rather create a copy and then edit that. You can then make copies of the drawing tools that utilizes your copy of the fills.

CC3+ allows you to select by lots of different criteria, such as the color the entity, the layer, the fill style, the entity tag, etc.

You'll find a description of this in the editing chapter of the user manual, and a more in-depth description here.

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.

Try to uninstall SS4 (using the standard add/remove programs in windows, as this will call upon the old installer cache) and reinstall using the new installer. Hopefully that will fix things. (Remember to reinstall the latest update when you are done)
