We've changed the behaviour of "select" command. If there is

select <some-survey>

only maps from <some-survey> survey are exported. This is very useful if
you have huge datasets. So look for the select command

select evening.soundriver

in your thconfig file. You've selected survey for export, where no maps
are given. You have to change it to "select soundriver", or use another

select elevator at soundriver

or remove all selects at all.

You've probably not noticed "Show" button in the area control :)))

This behaviour I "can not" change (I was also wondering). This is
because of BWidgets. You have to move "underlined cursor" to desired
position and press "Space". I'll look at it.

... and in the new version, if the rock border will be closed-line
 - it will be filled with background color and overlap all items below.
Like this, you'll be able to draw rocks on some area (sand, debris, water) also.

OK, I've added it into output en_UK translation (to the legend). It
would be also very easy to add it into input parsing table, but I'm not
sure, whether it makes sense (a lot of equivalents can lead to chaos).
You have to decide (at least, we support centreline/centerline so I
think pitch/pit could be also supported, because pitch is quite
important. But I'm not sure about popcorn (cauliflowercalcite in UIS
signatures :)) or other items like that...

Hope this helps,
