Missing text

I'm a new user of Mushclient (for all of a couple of days). For the most part, I enjoy using it, as it's a bit more full-featured than the Gmud I've been using for the past decade or more. However, I have come across one problem that I haven't been able to puzzle out.

Everything seems to be working fine, but when I look at myself, my description (and presumably that of others, though the playerbase is small and I've not yet had a chance to test that, instead opting to remain isolated while getting everything tweaked) does not appear.

I seem to remember there being an option to change the colors of specific types of text (exits, etc.), but I can't find it now that I've got the world set up. Everything else comes through just fine, as far as I've seen. This is the only issue I've run across. It acts like when, in Gmud, black text shows up on the black background, blending in and becoming unselectable. If I could alter this to display in the normal text colors, it would be very helpful. Changing the background color does not help.

Oh. Version is 4.73.

Changing the colours of certain sorts of lines is normally done by using a trigger.

How would I do that, then, without knowing what the triggering line of text should be? The only thing preceding the description is a prompt (which would change all colors), and there's nothing constant about the descriptions in the mud I play except at the very end (literally the last few words).
