[Evolution] calendar events not being notified

[Russell Fulton <r fulton auckland ac nz>]

Hi Folks,
        I'm using evo 1.4.6 on FC2 and it has suddenly stopped alerting on
calendar events -- I'm not exactly sure when this started happening. 
The alarm notify process seems to be running:

[rful011 bloodnok rful011]$ ps fax | grep evo
 2521 ?        S      0:03 /usr/libexec/evolution/1.4/evolution-alarm-notify 
--oaf-activate-iid=OAFIID:GNOME_Evolution_Calendar_AlarmNotify_Factory --oaf-ior-fd=43
11438 pts/1    R      0:00  |   \_ grep evo
 2632 ?        S      0:15 /usr/libexec/evolution/1.4/evolution-wombat 
--oaf-activate-iid=OAFIID:GNOME_Evolution_Wombat_ServerFactory --oaf-ior-fd=42
 8979 ?        S      3:19 evolution

Any idea what is wrong or what I can do to diagnose the problem?

I'm starting to catch flack for missing so many meetings and the windows
folk keep telling me to use a real mailer ;)
