I change in "Look and Feel" menu -> Icon. A new selected icon is created in the application list. But the previous icon remains. Each icon change adds a copy of tha application to the shell. Rebooting OS don't fix bug.
PS. This version app from this site (activation from email)
I'm change the application icon, but a new one appears next to the old one.
Duplicates don't disappear. Only reinstall app.
