Please clarify. including a screenshot may help. Is this an addon?

Dear Mr David.　 I appreciate your comments.

I attach a screenshot and Explanatory note added.

It is not an ADDON.

Best regards,

would you be able to create a larger screenshot? This is too small to read. Thank you.

How about this screenshot image?

Thanks in advance.

Thank you. That is a bug in the Daily version. What version are you using?

Thank you very much. I understand now. I am using the latest version. Version 137.0 Released April, 2025

The final purpose of this case was to write in text format, not HTML format. I did some research and made the changes in the “editor”, and it worked.

I will try to use the beta version available.

Thank you very much for your help.

Correction: there is not a bug, it's just that the box is sensitive to whether sig is attached. Since you're at 137, your okay and no need to use the beta. My earlier response was obviously confusing, My regrets,

I doubt the beta is any better

david, I don't understand what you mean by "the box is sensitive to whether sig is attached"

When I clicked to edit the box and the tick box is set to use attached sig, the box can't be edited.

Dear　Mr.david and Mr. Wayne.

I took some advices and did a lot of research. As a result, we thought that there was still some strange configuration that was causing the lag, and a full uninstall solved the problem.

(The Version is "Release(Recomend)", not beta....) Once again, thank you very much.
