Secure mode

secure mode
Secure mode is a modus in which game maker does not "execute" it's programs. The setting can be found under "preferences->general" run games in secure mode, not executing programs. By default it is unchecked.

If checked, any game created with Game Maker that runs on your machine will not be allowed to execute external programs or change or delete files at a place different from the game location. (This is a safeguard against trojan horses although success is not guaranteed.) Checking this means that games that utilizes external files etc. won't be running correctly. The setting only works while Game Maker is running.

Contrary to what the manual says, if you have gamemaker open -and set it to run in secure mode-, also other executables created with the same version of Game Maker are run in secure made.
