What's the context of your concern? Are you worried about selling something to someone or running a bitcoin exchange? The system itself sorts out most of the double-spend risks, you can add some extra protection for yourself by waiting for a number of confirmations in the blockchain. You can read more about double spending on the wiki: https://en.bitcoin.it/wiki/Double-spending (https://en.bitcoin.it/wiki/Double-spending)

You can always wait for 1 confirmation. If you don't want to do that, the most practical way would be to to check the transaction from 2 other sources like blockchain.info and some other explorer site.

Wait for 6 confirmations if you are really worried.

One confirmation is enough at all by the way. After one confirmation, the other transaction can't be spent anymore (depends on the client).

Blockchain.info is really buggy , sometimes the TX doesn't show any confirmation, sometimes unmined blocks get added, I suggest any other, Blocktrail.com or Blockr.io.

Actually Blockchain always work in my opinion and it's instantly. Maybe you have to reload the Blockexplorer to get the updated data. Blockchain works for me always fine :)

yes,i think blockchain works fine,maybe the cause of double spend is the internet connection,so the website seems buggy

Wait on a number of confirmations based on how much you trust the person to not double spend. 1 confirmation is really enough though, any more and you run the risk of annoying people with long waiting times of an hour on average to wait on their funds.

For trading/selling . Just wait for atleast 2 confirmations before sending the things . It is very hard and almost impossible for a double spend to reach even 2 confirmations.
