I have had SW Stats for a while but now that 2.3 is live, everything is the same BUT my settings window when opened is off the screen...and i can't move it since the top of it is above the UI.

Have you tried to delete the lua file for SW in your WTF folder for that character? Doing so should reset all the conigurations for it.

I'm having the same problem. Tried the suggestion. Didn't work. Any other ideas?

I had it too and i found it easiest to just reset SWStats entirely whilst being ingame. It's quite easy to get all the settings back if you're familiar with the addon, so that wouldn't have to pose too much of a problem.

Type /sws and see list for able commands. There is command to reset positions of all swtats windows.

try typing /swstats resetwin
