While the wallet (v3.10.3) does have a known issue with sync performance, it almost always will launch, sync and ondex entirely on its own with no manual intervention. This process may take an extended period of time, or may seem to have "frozen" or "hung up".
There is a process to "bootstrap", or bring the blockchain up to date by manually downloading and extracting trusted blockchain data files instead of syncing from the network. We would note to interested Reddheads that while part of this process of sycning includes downloading or acquiring the actual blockchain files, which can be done peer-to-peer (normally) or by using a trusted copy (boostrapping), there is a second part to the process of actually reading and processing all the blocks for transactions of interest to your particular wallet. Just bootstrapping accomplishes half of this process; the second half may still take some time and should NOT be interrupted or the client forced to quit without good reason.
Forcing the ReddCoin wallet to quit in the midst of blockchain operations does risk data corruption or loss as the wallet tries to record ata to what is essentially a small database on your computer. If the data is not written correctly, problems occur, and potential fund loss has been known to happen.
DO NOT FORCE QUIT OR KILL YOUR WALLET IF YOU CAN AVOID DOING SO.
