RickT4n created an issue (vim/vim#20880)

Steps to reproduce

GVIM90 on Cadence Design Entry HDL
When selecting text, and invoking GVIM90 as the external text editor, GVIM90 would launch with a window with the selected text. The changes can be made in GVIM and then saved, and Cadence Design Entry HDL would get the changed text.
GVIM92 will only open a blank window.

Expected behaviour

Expected behavior is GVIM92 would launch a window with the selected text

Version of Vim

gvim_9.2.0000

Environment

Windows 11 Enterprise

not enough information. What filename was passed to Vim? Are you able to access it?

The filename I see on the window is some variation of edita<some hex numbers>
It whatever Cadence Design Entry HDL gives it, and its never the same.
My guess is the selected text is given a buffer by HDL and that is passed to the external text editor.
Would a video of gvim90 working and gvim92 not working help?

Not a video, but a couple of filenames that gvim (and other text editors) are passed from Cadence Design Entry HDL
Definitely gvim92 is doing something different than gvim90.
Gvim90 opens a window with the selected text to change.
Gvim92 opens a window, but it's a blank window [NEW]

For Run#2 with gvim92.exe
