In version 1.1.0. the Stop button, when scanning for subtitles (the first scan screen) doesn't work.
Also, I've imported my settings from the old BETA and suddenly the program searched for subs in other maps within my selected map. I didn't checked this box in the old BETA and I didn't checked the box in the new BETA. When I selected my main map again and left the checkbox (search maps within maps) unchecked, it worked.
