DS Lab Demo The DS Lab Demonstration requires 6 megabytes of space on your hard disk to install. The Action player used is slow to load the demonstration (it may take a few minutes). Please be patient. The demo itself takes approximately 15 minutes to run at its own pace. To speed up the process, use the "Next" button. Should you wish to view the previous frame again, use the "Previous" button. To spend a little more time viewing the current frame, press the "Pause/Continue" button. Press it again when you are ready to continue the demo. If your system returns an error message regarding insufficient temporary disk space, this is due to either too little space on the hard disk to which your Windows TEMP environment variable is assigned, or you have the TEMP environment variable assigned to a RAM disk which is too small. The solution is too free up disk space or to assign more RAM to our RAM disk. For more information on the temp variable, look up TEMP environment variable in your Windows manual.
