I've got a SP2013 list with a Single Line of Text field that isn't accepting any input from the keyboard. The other fields work fine, and I can select the single line of text field, but nothing appears when I type. This only happens in IE11, but the field works in Chrome. I'm not sure what's happening, as this worked fine last week, and there haven't been any changes since then that I'm aware of.
Any ideas on what the issue could be?
