I have tried it on Fedora 17 and on Fedora 19.
Fedora might maybe have some kind of problem with the concept of a "system tray", which seems to be a mac and/or windows concept.
However, it might be the case that more grandmas use windows or mac than use various types of Linux? (Is Android a type of Linux?) so maybe that is okay?
FellowTraveler basically just says Fedora must be using a broken windowing system or something.
1. We have many users on Linux who are able to use it just fine -- it's not a problem with Linux.
2. Google this: "system tray" broken on Fedora.
Notice all the complaints and bug reports related to this issue on Fedora. (For other apps, like Dropbox, Skype, etc.)
3. Google these:
A. solved "system tray" fedora
B how to fix "system tray" fedora
(You can see there are many various solutions for this as well.)

MarkM:
I think the problem is that Gnome may have put the systray into an extension.
We discussed this on IRC previously -- have you installed the systray extension?
I recommend you get a windowing system that works but otherwise you might try the extensions, such as:

P.S. most Linux users do not have this problem. lclc, randy, da2ce7, and others have not reported any problems, so it's not specific to Linux. And of course the problem doesn't occur on Mac or Windows either.
