Unable to use 'capture()' function if Sikulix-IDE is not running

When I try to use the 'capture()' keyword outside of the Sikulix-IDE I get the following error:

>>> print capture(Region(0, 0, 50, 50))

I think the problem is that the "\Sikulix\" folder is not being created.

Using 'capture()' in the Sikulix-IDE works. And, while the IDE is running, I can see that the "\Sikulix\" folder exists. Additionally, 'capture()' works from external Jython scripts *so long as* the IDE is running.

But once I close the IDE, "\Sikulix\" gets deleted, and 'capture()' ceases to work from external scripts.
