IScreenPlugin.Activate() being called twice

[ACTCMS]

EDIT: Panic over - I figured it out...

I’ve found a problem which I’m struggling with...

When my IScreenPlugin kicks in as a screensaver, it sometimes gets activated, deactivated then activated in quick succession...

Code:

[FONT=Arial][SIZE=2][FONT=Arial]2011-06-03 00:23:14.971            [DEBUG][1]       SSPlus Activate: completed in 00:00:00.1406295[/FONT][/SIZE][/FONT]

I don't see any errors in the log. Any ideas of what sort of thing might cause this behaviour?
