When Auto Save/Crash Protection is enabled, PureVision will take a snapshot of the current Project at a set interval.
If PureVision does not shut down properly you will have the option to restore this snapshot when PureVision is restarted.
Setting this option to 0 (zero) will disable Auto Save.
Setting this number to 30 will tell PureVision to save every 30 seconds and a save will only occur if a change has been made.
NOTE: Enabling this option may impact performance due to disk writes at set intervals.
