I will fix Q2. As for Q3, The check box will be reset on the next beta version (beta 5). As for Q4, currently, EmEditor can’t highlight multiline keywords.
I can’t reproduce Q1, Q5, and Q6. There are lots of conditions that affect test results. Can you make your test case as simple as possible, for example, the symbol “%%” matters? What about “abc”? Please make your test cases as simple as possible, and please email me sample files with detailed explanation as to how to reproduce the problem at firstname.lastname@example.org, along with your registry file exported at HKEY_CURRENT_USER\Software\EmSoft. (Please zip all files.)
After you export your registry, you might want to select “Tools” -> “Quick Launch” -> “Rest all Settings” to reset your settings and try again and see if you can reproduce the problem.
