This stack contains the script code required to install a screen save routine into your home card. Since I use Hypercard exclusively as my desktop I wrote this to free up a Desk Accessory slot. The HyperSleep will timeout if the mouse has not been moved for 60 seconds. Once the time out has occurred simply press the mouse button and you are returned to your previous card.
Installation consists of modifying the script of the first home card 'idle' routine.
You could also install this routime in any other stack to do the timeout function.
