Description of problem:
After writing my long comment I unfortunately clicked on "Close" button and my
long comment has been destroyed without warning. This window should contains a
dirty flag to avoid a such accident.

Imagine - I want to write a single comment:
It means to click on two buttons "Save" and then "Close" button. And what
happens when I make mistake in the right sequence?

How to write descripton for more than 300 images without to be clicked to death?

Version-Release number of selected component (if applicable):
gthumb-2.7.8-3.fc6

How reproducible:
always
