stalonetray + koofr = there is no icon

[NailGit]

Hi,
I use the Koofr cloud with the local client. When I start it, the Koofr icon appears in the taskbar.
However, two weeks ago, the icon suddenly disappeared from the tray. Then, one week ago, the icon reappeared, but today it disappeared again. I verified in the Ubuntu tray, and there is no problem; the icon is still in the Ubuntu tray.
What is the root of the problem?

My staronetrayrc

decorations none
dockapp_mode simple
geometry 6x3+0-0
icon_size 32
slot_size 40
kludges force_icons_size
max_geometry 6x3
parent_bg true
transparent false
icon_gravity SE
grow_gravity SE
#for fvwm
no_shrink true
#skip_taskbar true

I found (with AI :)) the root of the problem. I have to kill daemon of koofr: pkill -9 storagegui and then start again storagegui.
