Icewm saves its default config files in /usr/share/icewm. configuration, menu defaults, etc..all go here. When icewm is re-emerged, these files get overwritten without warning.
from morfic in irc chat: <morfic_> Icewm saves its default config files in /usr/share/icewm. configuration, menu defaults, etc..all go here. When icewm is re-emerged, these files get overwritten without warning. <==== this is true for any distro, which is why the files tell you to copy them to /etc/icewm/* or ~/.icewm/* please read the docs
