Hi scullhead, I saw your post in an email alert, but could not find the post. Liftpizzas found an alternative block removal. We both use left shift as the "Down" key, and nothing would make the right shift key work for block removal. Somehow, the "Run" key works. So, it's "Run" + Right mouse click. for me, I have it mapped to caps lock. Hope it works, I was dead in the water and Lift saved my game! Cheers.
