We saw this also with FC3/FC4 and RHEL4.
EDM uses "XRaiseWindow" and it was not being honored under KDE.
It's called "focus stealing prevention", see e.g.
http://mail.gnome.org/archives/wm-spec-list/2003-May/msg00013.html . A
short description is that only the user (i.e. taskbar etc.) and the most
recently activated application are allowed to raise or focus windows,
requests from inactive applications are not honored.
Solution:
========================================================================
Turn it off globally in Alt+F3/Configure/Advanced or just specifically
for the app in Alt+F3/Advanced/Special settings/Workarounds (force to
none).
Also, you can do this from the KDE control center.
-- Select Desktop
-- Select Window Behavior
-- Select the "Advanced tab"
-- Now choose None for "Focus stealing prevention level"
===========================================================================
