I've just installed gnome-tweak-tool on Ubuntu 17.10 and some themes to customize my desktop. In the tab Appearance > Themes > Applications there is a dropdown menu to choose another theme, but when I click (for a long time) on it, there is no dropdown. It's strange because the dropdowns just below (cursor, icons) works.
I did:
sudo apt-get purge gnome-tweak-tool && sudo apt-get install gnome-tweak-tool
But the problem is still here. How to fix it ?
