Dropbox icon keeps disappearing from system tray.

We are having the same issue - however we are seeing the complete App not work. Any suggestions on what you did to solve this?

I uninstalled classic shell. So it appears to be working now, but I will keep you informed.

Same problem. No solution.

I wrote the initial problem and couldn't get it fixed. So I decided to work at getting the answer as it was really upsetting me.

Here are the steps to follow:
The small white arrow in the System Tray indicates that some icons are hidden. If the arrow is missing, that means that all application icons are shown.
If the small white arrow is not in the System Tray, follow these steps:
1. Right-click the System Tray > Properties.
2. Under the Taskbar tab, click Customize.
3. UNCHECK Always Show All Icons. Now the small white arrow will appear in the System Tray.
4. Click OK twice.
5. Now launch www. Dropbox.com.
6. The Dropbox icon will appear in the System Tray!!!! (Now we need to keep it there.)
7. Right-click the System Tray > Properties.
8. Under the Taskbar tab, click Customize.
9. In the list of applications, locate the Dropbox application. Click Show Icon and Notifications.
10. Click OK twice.
11. The Dropbox icon still appears in the System Tray.
12. Close the Dropbox website.
13. The Dropbox icon is still there!!

I hope I remembered all the steps. Good luck!

I'm running Chrome on a MacPro...no arrow in system tray, no Dropbox icon (which I need to click to get to preferences so I can unlimit my upload speed) and right-clicking up there has no effect.  Me?  Man, I just want fo get my upload speed to something *close* to the 75% Dropbox promises...very frustrating...

OK...lucky enough I have a couple of PC desktops and I *did* find the icon in the system tray and thusly changed my settings...however, *still* very slow...

I was having the same/similar issue and icon did not show up either, on a PC.
However:

1.- I open the 'Windows Explorer' and 'search' for Dropbox.

2.- I clicked the application in order to open it and, voila, it came up, and it is loading as usual.

I guess it may be the same on a MAC. Try then to Applications and open Dropbox from there, on a MAC!

Hope either Charlotte's (gave me the full hint on how to proceed!!) or mine help!

On Windows 7 Dropbox stucks: no window, no tray icon, though I can see the process in TaskManager. I reinstalled it many times, cleared his data folders, switched off from server

Follow the steps in my Feb 4, 2015 submission. For me, the problem has been resolved.

I have two dropbox icons that are always there;

• A blue icon is always pinned to the bottom left task bar.
• A white icon always appears in the bottom right system tray. 

Note: If you right click the white icon, you will see two mini icons on the bottom: a file folder and a world globe. The file folder launches your local dropbox folder and the world globe launches your dropbox web site. Whatever you do on one should update the other. 

Hope this helps.
