+Thanks to **Sulix** who posted an analysis of the bug on the [Steam Forum](https://steamcommunity.com/app/221380/discussions/2/622954302095447538/#c154645539343670235).

+Thanks to Microsoft Research for the Detours library and the excellent accompanying samples. `dll_inject.cpp` was derived directly from the `withdll` example, and `fix_scrollbug.cpp` was derived by modifying one of the other examples.
