Icon Manager Icon in Debian

I talked to Peter at Mesa today about a problem I am having Linux Debian CNC.
He thought there may be a bug in the version I am running. 
He thinks it is making too many icons in the background so I can't open up any of my apps.
On the top panel is full of connection icons. I always thought that was strange, but everything worked fine until lately.
Now none of the icon work.
Has anyone heard of this?
Thanks

An older version of the official ISO had such issues, so if still suing that it would be very good to upgrade to 2.9.2 ISO.
That does imply formatting the drive so do make a backup of the config on a USB.
