Import Nate for Linux users.
Around 2020 Linux distributions started shipping systems either without a System
Tray or with one that has strictly limited capabilities. All in the name of
"reducing clutter". This means you may not be able to get different events
for Left and Right click, possibly no Hints or animated icons. See the FPC
wiki pages for more information.
