#64 Setup remains to be open

This is only a minor bug, that still can bother though.
After installing the GCK software, the installer asks
if we wish to launch GCK now. The checkbox is on by
default.
And after pressing "Finish"/"Ok" the GCK is instantly
loaded, *but* the setup window remains open, although
in the background it can be seen in the Taskbar.
Jack I think this is your field.
