I see no menu after clicking on the Dropbox tray icon on Fedora 43.

Dear Walter, thanks so much for trying to help! Well, I've got some news: I've tried to re-install the Dropbox daemon through the command line (using "live help" help from MS Co-pilot)... after much "ping-pong" between "my output" and what the Co-Pilot was asking me to do, the Dropbox daemon got re-installed. 

After a couple of re-starts, the menu finally appeared. So, I can now see that it originally "installed" version v240.3.8407. I've noticed that upon a restart (or a fresh start), the menu does not always appear (though the blue sync symbol comes on, and the blue/green symbols on the sync folders do appear as per normal).

At some point, it appeared again (and when it appears, all menu options are initially "grey" (inactive), and after a minute or two they become black (active), and then they work fine.

Today, the version got updated from v240.3.8407 to v240.3.8460. After the first 1-2 restarts, system tray icon still didn't show-up, however when I've checked Fedora's Apps for any system-updates, it did find an update. Installing the Fedora update and following another re-start, tray icon menu re-appeared and works correctly (which is why I could see the new version installed).

All in all, it appears somewhat temperamental but eventually OK. Will keep an eye on it and I intend to install Dropbox again on my other ThinkPad T430s, also running Fedora 43 and see what happens.

What I find scary, is that I've only managed to install it using Co-Pilot (and it took me nearly 2 hours, exchanging command outputs, till Co-Pilot eventually spotted "the right way" (too complex for me to remember).

Will keep the community posted. Very grateful for all suggestions.

Kind regards,
Christos
