I have managed to select 'Gimp' as bitmap editing tool (Tool path: Z:\usr\bin\gimp). Now when I choose 'Edit subpic with external tool' 'Gimp' is launched but I get the message: <Opening of "/usr/bin/C:\users\utente\Temp\tempbitmap.bmp" has failed: cannot open '/usr/bin/C:\users\utente\Temp\tempbitmap.bmp' in read mode: non existing file or directory> I hope my translation from Italian is correct.
