Does this still occur after a successful update?Now everytime i run it, even after a reboot (!), when i click enable it shows an empty dialog. Actually all dialogs shown are empty.
It doesn't start at boot. It can be done by adding "/usr/sbin/ipblock -s" to /etc/rc.local. But to use the GUI it would require to stop ipblock manually (sudo ipblock -d).Also does it run at startup?
Yes. Running it in background can be done by using ipblock from the command-line (man 8 ipblock).Do i have to keep the window open for it to block?
