Mine does not freeze, but does lag during a transaction from time to time. Other wallets seem to do the same. But never a full freeze.


also: If you have a wallet.dat file with a very large transaction history, sometimes that can cause problems. a couple of startup commands that can help are premine-qt -rescan (or) premine-qt -reindex. (warning, the last one may take awhile) if all else fails, backup your wallet.dat, and send the coins to a freshly generated wallet.dat file. This assumes that the wallet.dat file is the source of your problem, which may not even be the case.
