Can't close Calamus in a proper way

Since some time it's impossible to close Calamus in the usual way.
When I close Calamus I get this:

I use Calamus SL 2006 R8.
Calamus uses 900 MB ram and 1 core

My setup is as follows:
Windows 7 home premium, service pack 1
HP p6-2030be
Intel Core i5-2500 cpu 3.30 GHz
8 GB RAM64 bits

Avast antivirus free version (up to date)
Zone alarm (latest version)

I wonder if there is a way to cure this?

How do you ensure that Calamus SL only uses 1 core?

I've followed this link <URL:http://btoforums.com/showthread.php?t=2875%3E> to make Calamus use only 1 core.

Here is another way how to make sure that Calamus only uses one kernel (sorry, but it is from the German Calamus forum):

I've tried the taskassign methode but alas no cure. I start to think another recently installed/updated program is interfering with Calamus. I noticed in the German Calamus forum someone have had a similar problem. If I understand it well it turned out to be a graphic program.

Kind regards,
Martin
