A week ago, I pressed a weird combination of keys and all of the sudden my Jupyter notebook changed views. The scroll bars on the sides of each cell had quadrupled in size. I tried reverting it, but was unable to find a way. I then tried to close the note book, reset the notebook, uninstall/reinstall anaconda, to no avail. What ended up fixing it was unintalling/ reinstalling chrome. All of the sudden my view was back to normal- for a few days. It went back and now uninstalling chrome does not work.
