This overcomes some of the problems I was having with the IDE.
Open khotkeys and create and define a hotkey, on the action tab, paste:
wmiface findNormalWindows "" " Lazarus" "" "" 0 false | \
while read ln; do
wmiface forceActiveWindow $ln
done
Into the command/url box.
I defined meta+z, when pressed, it brings all Lazarus windows to the front.
I had to install wmiface, but it was in the Mandriva repos, so it will probably be in other distros.
