Hi, longtime user of Marked 2. Just purchased M3. On M2, no problem scrolling on a preview of a 1MB text document with no bells and whistles. On M3, I was sure to disable memory intensive features for large docs, as I did with M2. I get a kernel panic beachball when I preview a 1MB doc (a .txt file) and attempt to scroll down. Is there a setting I am missing? Using default MultiMarkdown processor.
