HOWTO: How do I stop my wallet from using SyncPro to sync?
To stop synchronizing a wallet with SyncPro, go to Synchronize -> Setup while in the desktop version of eWallet. Change the sync direction for any devices in the list to none.
To stop (or change) synchronization with a different file than the one you have open, go to Synchronize -> Synchronized Wallets. Then pick the wallet you want to change and click the Change button.
