FKEY to refresh the screen in Classic Mac OS.
The program is an FKEY. To install:
- Make a backup of your System file.
- Open your live System file with ResEdit and open the FKEY resource.
- Open BitRefresh.rsrc with ResEdit and open the FKEY resource.
- Copy and paste the FKEY resource ID 9 "BitRefresh" into the FKEY resource of your System file.
- Save the System file and quit ResEdit. There is no need to restart.
Since this is an FKEY with ID number 9, it is invoked by pressing Command-Shift-9. You can use any number between 5 and 9 for the FKEY if you wish, just change its ID number in your System file.
