This is still the same with EmEditor v12.0.11.

Since Yutaka didn’t response on this
I do not know if is this an bug?

If yes, can this be improved please?

If No, what would be the indicated workaround please?

Hi Yutaka, i have an problem with replacing text
in an column/block selection from an macro.

Tested with 11.0.5 and 11.1.7

My problem:
if i take the block selected text,
and manipulate it with an macro,
the macro works correct
but the text replacement in the document
replaces all selected lines
with the replacement of the first line only.
