Hi Patrick,
Could you clarify whether you searched for “aRefNEQ” before or after making that selection? If possible, please share the steps to reproduce the issue.
It also looks like you have Virtual Space enabled (on the General page of the configuration settings). Is that correct?
Lastly, could you try a fresh install of the latest preview portable version and let me know if you can still reproduce the issue?
Thank you,
Hello Yutaka,
I wrote a macro that triggers the error:
hDataNull_error_demo.jseeEmEditor 25.3.910 still has the issue.
Settings:
● Virtual Space is enabled.
● In the find dialogue: Treat CR and LF separately must be enabled.
● Encoding: UTF-8 without BOM
● Newline character: “LF”Many thanks!
