This addresses an issue when collapsing the Button Master window (imgui Begin/End calls). This also updates some of the script dependencies (you will have to move stuff around - see below).
Instructions -
1) Remove the lua/buttonmaster folder (not your config/ButtonMaster.ini!!!)
2) Copy the contents of the lib/ folder from the zip to your lua/lib directory (create the lua/lib directory if you don't have it yet)
You should now have lua/lib/ed/utils.lua, lua/lib/LIP.lua
3) Copy buttonmaster.lua to your lua/ directory
Note: You now start the script as /lua run buttonmaster
