If two alarms are added which both have the same time, only one of them
will be executed.

If a sound alarm is running whilst the applet is killed the sound will
keep playing. It shouldn't, but it does !!!.

!!! Pre 0.8.6
When using with GTK+ 1.2.4 the applet can cause an IMLIB_ERROR if the 
pixmap engine is being used when the popup window is selected. I think
this is because of GTK+ and not the applet. It is because for some reason
a widget is being allocated of too greater size.
