Text: An unsigned application from the location below is requesting permission to run. (Warning icon) Location: http://www.greenfoot.org Running unsigned applications like this will be blocked in a future release because it is potentially unsafe and a security risk. Link: More Information Select the box below, then click run to start the application (checkbox) I accept the risk and want to run this app. ('Run' button) ('Cancel' button) ********************************* What would I have to do once I am blocked from running unsigned apps?
