So I created a new project and code blocks seems to have lost it. As I said above, I cannot backspace except for white space. Any code I highlight is deleted. Most of the color coding and auto format features are gone, and it is just really unstable. Trying to play with it, C::B will crash two or three minutes in every time.
This is effecting my old projects as well, so I assume I messed with some setting on accident but have no idea what I did. Also, it seems weird that a setting change would cause the program to crash constantly. I apologize if it is an amateur question, I tried searching but could not find any similar threads.
