Pinned extra meny

Extra pinned meny.

The following image shows how this normally looks.
In your screen shot it looks as if the "Properties" panel at the bottom is very small and parts of it (?) are somehow showing at the top of the Thesaurus Manager window, for some reason...?

Left-click and drag the dark border above the "Properties" panel and resize it to make it larger, so it can actually show the data required.
