Important Info
Okay, so I've been looking into the "not responding" bug, and it turns out this may not actually be a bug but an error in one of my scripts. There's a Link script called "ThePartOfYouThatWantsToRun.txt". If you navigate to the Scripts tab in the settings Menu, then the Link tab and click on that Link Script, you can use the "Open Script" button to open it in notepad.
On the second line, you'll notice the Command @AFKOn. That shouldn't be in this script, I don't know how it got in there

Any time Tease AI comes across this script, it would activate AFK mode which would make the domme not respond to anything, but the script never turns it back off, so it persists through the rest of the program. Safewords overrule AFK mode, but Safewords wouldn't get you out of multiple choice branches if @AFK mode was on.
Please delete the Command @AFKOn in the "ThePartOfYouThatWantsToRun" Link script, and let me know if the program hangs on you again. There could be other errors in different scripts, but the only two other scripts with @AFKOn that come with default Wicked Tease check out.
I will update the Wicked Tease archive on the front page, as well as include a small patch here if you don't want to worry about editing the file manually. Just extract this into the Tease AI root folder and it will put a corrected Link script in the appropriate Wicked Tease folder
Let me know how the program works after this, and if you still have a not responding problem, try to tell me what scripts where happening at the time if you can
