question about Ctrl-R refresh

[Claudio Fischer <claudio fischer freenet de>]

Hi,

I have a question about the command „Aktualisieren“ Ctrl-R, refresh in 
english?:
I compare two files. Then I edit something in the left file and the 
dirty-flag switches on, means has changed, needs saving = Ok.
If I now hit Ctrl-R to rescan, the dirty-flag goes away and if I now 
close the files, meld does not ask to save the file and the changes are 
lost.
Is this by purpose or am I missing something?

Regards,
Claudio
