It's possible to hide the singleprompt by accidentally scrolling over it. In some cases, you can do this in a way that's subtle enough to not even be able to notice that you've done it, and you just think the Singleprompt vanished. Toggling it does not resolve this, only restarting Mudlet does.

I really don't understand the UI-y elements of Mudlet at the moment, so not sure if there's ~something we can do to prevent this from being able to happen, or to at least make toggling singleprompt bring it back?
