I've installed Linux Mint 17 with Cinnamon.
I tried to make GNote, Thunderbird and Skype autorun on system startup minimized to tray. I made them autoruned with
Startup application program. Then I made GNote and Skype minimize into tray with their menu settings. And I had to install a couple of add-ons(
MinimizeToTray revived and
firetray. because the former didn't work) on Thinderbird to make it minimizable to tray.
After that at first it worked first time but then a strange bug appeared. Every time I minimize one of these programs to tray or they are minimized with startup their tray icons don't appear. They appear to be working in processes list, but no tray icon and no icon on panel as well. So it actually gets to tray but no icon appears on the other hand.
Is there any way explain it and repair the tray? Tray worked but then it got broken in that way.
