I'm personally NOT running borderless mode, I'm in windowed mode. And I'm pretty sure it doesn't just work with tailor. But with the others aswell.
Does it open the context menu on the REing tool? Since this script indeed runs alittle fast, because this was the speed it worked perfect for me. But it has error checking, so it should redo it's step it it failed it.
Please tell me the exact moment it doesn't proceed.
Oh, and I have to ask: Are you using the downloaded text file, not the copy pasted from my original first post? And do you have the latest autoit version?
EDIT:
I just realised. Do you have an empty backpack of the size of your inventory, BEHIND your inventory. And the opacity of the windows maxed?
EDIT2:
Don't forget to turn off "Allow object icon rotation" in your options under interface in options
