I am using Eclipse version 2020-03 I don't want to use or upgrade to any other version for some reasons. I am opening a read only file. Whenever I double click on any line it shows me the below prompt. Ideally this popup should come when I try to type any word in there. However in my case, its showing that prompt even if I select a simple word. Its weird and irritating now.
How do I fix it? I want it to show this popup only when I try to actually edit the file.
PS: I have checked This question, but its not related to my issue.
