The fills for the DD3 corridor/room tools unfortunately cannot be set via the style, so they will always be the same as last time you use them. You need to manually just pick different options in those fill style boxes before using those tools in a new map. Only fills from the current style should be listed there.

Basically two ways to handle it:

• Don't start in a corner, start in the middle of a side length. As long as the starting and ending point is the same (as well as the angle of the two segments) it will meet up seamlessly.
• Turn it into a polygon. Draw it as normal, but don't do the final connecting segment. The use Path to Poly [CLOSEPATH] on the wall you just drew.

This is basically the way to handle this when you try to draw a closed shape with a line-type drawing tool, being city wall or dungeon room.

Have you tried running the latest update (Update 28) available from your registration page? Even if your CC3+ install is already at 3.98, the update fixes up other files in addition to the core program files, and can often fix weird issues like this. It is usually a good idea to install it as a last step after installing all add-ons (except the free monthly symbol sets, they should be the very last)

If that doesn't work, I recommend getting in contact with tech support, also available from your registration page.

Yea, there is actually a white polygon around most maps by default, on the SCREEN sheet, it is used to hide stuff that might be sticking outside the map border, since a drawing is technically borderless. But the printer will still see that as a valid area to include int he printing.

What you can do to avoid it is to print just the 'active window' instead of 'everything'. Before doing that, simply zoom in to your map, and maybe resize the CC3+ window accordingly so that the view only shows your actual map, nothing more. The best way do do this is to first use the Zoom Window command to define a tight rectangle around your map, and then resize the window afterwards, because CC3+ will remember the zoom you defined and always fit that part inside the window. Also remember, CC3+ do have the map in a separate inner document window, you can resize that instead of the main CC3+ window.

If you just want to fill the page, simply use the "fit to page" option in the print dialog, no need messing with precise scaling. CC3+ should fill whatever paper size your printer driver reports it is using.

For proper scaled maps, yes, just use 1" paper scale = 5' drawing distance. All you need to do to make that work properly is when making the map, treat the numbers you specify the map size in in the wizard as feet, and just work with the map in real scale, i.e. when a distance should be 5', Info -> distance should show that thing to be 5'.
