closing SW 2008 student edition

When I have worked with SW 2008 student edition (on a laptopwith vista 32bit) and I have closed the program, it sometimeshappens that after a while the program opens itself again. Evenafter a restart this sometimes happens.

Further more, when I close SW, there's still a process of SWrunning: swBOEngine.exe. When I reboot my laptop this proces isautomatically running.
I suppose that this process causes the problem, but how can I fixthis?
