When I look through my edited posts and click to read the description of a post, it covers my whole screen without a way to close it (unless I go into landscape). The menu can be closed, but it's a minor inconvenience that can cause some annoyance.

Go to advanced settings, then put
.desc-popup { width: 325px; margin-left: -180px; }
in the custom css box. Modify the numerical values to fit what your screen
