Using scim-1.4.14 (and scim-anthy-1.2.7) breaks WindowMaker: disables events on the ROOT window (e.g. right-click to show menu).
There is an old bug in Gentoo: https://bugs.gentoo.org/show_bug.cgi?id=434138 as well.
app-i18n/scim-1.4.11-r1 works fine
Thank you for reporting this. According to https://bugs.gentoo.org/show_bug.cgi?id=434138#c16 this should be fixed in version 1.4.16.
Yes, it is fixed, I just reconfirmed, sorry for the late response, forgot about this bugzilla.
