Weird bug with some SELECT queries

http://puu.sh/2vCqV


I notice this happens quite a bit when I try and copy and paste a SELECT query which returns data.

I'm not sure if this is intentionally put in so you can't copy paste, or if this is an issue that can be fixed.

"Grid editing error" is nothing critical. It just says you cannot edit the result. That means, pressing F2 on a cell starts a mechanism in HeidiSQL which tries to determine the name of the table in the resource returned from mysql_query(). If you have some calculated table like in your screenshot, HeidiSQL blocks editing. Same happens with a slight different error message if you have a join over two or more tables.
