Dopus keeps running in processes even after closed

I'm sure this has been asked before, but several searches didn't find anything.

I've noticed that once you start Dopus it stays running in processes even after it has been closed. (OS is XP). Any reason for this and can it be prevented. When you are running a portable version, you have to manually kill the process before you can release the flashdrive. Just an annoyance is all.

See this FAQ.

Thank You!
