I've recently started learning how to use PSOC Creator, so this may be an easy fix. I randomly cannot edit my main.c file, or any new text files I create. Not that I would want to, but I also tried editing the Cypress generated source code for my project and cannot edit that either. If I edit my main.c file in another editor and save it, the text file in PSOC Creator is updated. I've tried restarting the program, closing and reopening the file, etc.
I believe I am using the most updated version of Creator. Did I accidentally activate a type of locking feature?
