File Browser does not open (CTRL+F2) when started from another application

“… so whatever issue you’re having with your file is unrelated to
the Geeqie project, …”

An inaccurate statement. The issue has been acknowledged by the
Geeqie project, and they’re currently considering the augmentation to
the respective code/script file.

Thank you for your time.

Sincerely,

Roger
