Under Snapshots, you can determine whether your snapshots are taken in the foreground or background. Taking a snapshot is not an instantaneous process. Enabling background snapshots allows you to continue working while Workstation completes the snapshot process invisibly in the background.
Select Take and restore snapshots in the background to enable background snapshots.
Note: You must wait until Workstation finishes taking a snapshot before you engage in any more snapshot activity. If you select a snapshot in the Snapshot Manager before that snapshot is complete, Workstation displays an error message: The screen shot of the snapshot does not yet exist. Once Workstation has completed the snapshot, you can select the snapshot in the Snapshot Manager.
