I just updated it.
It's not clear anymore, but it's still kind of messed up.
It's show metro style minimize maximize and close, when you hover over it just right it changes to the default icons.
Actually I just remembered you can turn it off for firefox. I guess I should use chrome anyways.
Thanks for responding.
8.03 is an old build, you need to update to the latest version which is 8.12
I am unsure why yours is saying 8.03 if you just updated, but I suggest uninstalling WindowBlinds, rebooting and reinstalling it.
