[Warning]: cron Task(s) exceed time threshold

[joebordes]

when coreBOS shows the event popup screen, it looks for an image with the same name as the event to show in the popup, so each "activity type" has it's own icon. those icons must end with an "s", so you can find:

themes/images/Meetings.gif
themes/images/Calls.gif
...

if you are seeing that error without any name it is as if you had an event with no type. Not quite sure how that can happen. What I mean is that the image you are asking for does not exist
