So since yesterday, I've had this problem: When I'm typing in my .tex file, suddenly, Texmaker has become very laggy. Both with typing and with selecting text. So I've tried restarting, that didn't help. I thought that maybe my document was too big (even though it is only 68 lines), so, I tried opening a smaller document (only 20 lines), and it too was laggy when typing. I opened a new document, and it seemed fine, until it too got laggy after typing for 3 seconds. Even with complete gibberish (just a few random letters on each line), and without turning it into a file or even naming and saving it, it didn't remove the lag. But: I just downloaded a random file of 173 lines, including ones containing entire paragraphs, and it works fine.. No lag whatsoever. Any idea as to what might be my problem?
