From the query editor's ToolBar Allow Execute Query
From the toolbar that has the undo/redo, copy,paste,delete add an execute button there. I find that I having to o back to the ribbon's query button and then sometimes the ribbon is on another tab so I have to switch this first is a real pain and slows me down.
Fixed in Log Parser Lizard Version 5.0
We will add this menu command in the following release. In the meantime you can use F5 key to run the query from the editor.
