HeidiSQL crashes when many sql codes are submitted

I submitted with F9 a bunch of sqls. After several hours I got a Heidisql-crash (see attachements). I looked at the console with SHOW PROCESSLIST\G and it seems that the sqls are still running. These kind of crashes happenes to me seldom and only if the sqls takes several hours. My question: If HeidiSQL crashes this does not affect the submitted sqls? That is: if once submitted from HeidiSQL MySQL works independently? Thanks for answer.

(I use MariaDB 5.5, Windows 7)

Yes, exactly. The queries are still executed on the server. That's why you can sometimes see the old queries still in the process list after getting some disconnect.

Thanks for answer and for HeidiSQL, my favourite SQL-Tool.
