Backup : error messages and a suggestion

Hello,

First, thank's for this great soft ... very practice and usefull

I have something strange with error messages for a backup, still result is ok !
-If I do a jobname ("test") on backup. No problem, perfect result.

-If I do in "script" : Backup "test" : I have an error message : "There was an error reading from the jobs file, please check it is not set as read only or in use"
I put "no file as read only" for toucan\*.*, it was the same and not in use exept toucan himself. (still result is ok, archive is created and correct)

- (same pb and maybe an other)If I use in command line (that I really want in final)
toucan.exe "test", i have 2 error messages. The second is the same that before, and the first is "Can't load image from file 'addvar.png': file does not exist" with the same message, 2 times, with hour, in details.
But I have addvar.png in Toucan\App\toucan\.
(again the result is ok)

I have also a suggestion : To add an option in Backup to check the archives at the end. (the "-t" parameter of 7za)
Maybe this is what we have at the end of progress report "Everything is Ok", but i'm not sure .

Thanks for all
