I click download and the dialog defaults to open

I'm trying a few scripts on the editor, when i click download a dialogue opens and offers me the options for my .hex file of open in text editor or dowmload. When I use make code blocks to download a .hex file the option defaults to save under the Python editor it defaults to open.
