EPA Taskbox

I created a Process with a Human Activity, in the Proces Monitor i can see that the process is working but i can't see the Taskbox. Do I have to turn it on somewhere?

To get the Taskbox displayed on an e-space, you have to goto
here you can select the e-spaces that can display the Taskbox

Activated the EPA on selected eSpace but it still doesn't show? I also tried to restore original configuration (show for all eSpaces) but this doesn't work either.
