#23 PreviousTask is causing exit

[Max Lindner]

I have this in my actions file:

PreviousTask : KeyPress = Left &
Control_L & !Alt_L,

when I login with kdm, start Mozilla and then after
mozilla finished starting up, press Control_L & Left,
waimea quits or crashes or whatever and takes me back
to kdm.

Could it be, that waimea is recognizing kdm as
PreviousTask?

When I'm hitting the Keys for NextTask nothing happens,
this is good so ;)
