At Ease 4.0.x and HP Printer Drivers

I get the message, "Items for <user name>", remaining up on the desktop after logging out for each user that was logged on; the users are all members of restricted Finder workgroups. Also, sometimes I get a dialog asking me to rename the HP printer when I logout of At Ease.

These simptoms only seem to occur on computers with HP Printer drivers installed. Is there anything I can do to prevent this?
At Ease 5.0 address this issue with Hewlett Packard (HP) Printer drivers.
