Any suggestions?  I'm showing 152474 blocks right now at the bottom of my wallet.  Is this normal?  Might the problem be that Mt. Gox is slow in broadcasting?

Thanks in advance for you assistance!

I sent a bunch of bitcoins to the computer on my other wallet and they haven't transferred to the other computer yet.  HOWEVER, they have been deducted.  What do I do to get them back or cancel the transaction?

FWIW, I've saved the key string.  PLEASE HELP!

I transferred bitcoins to my other computer and am scared I will lose them.  I'm using my wireless card on my other computer.  I have the key string saved to a word file.

Will this transaction "time out" if it hasn't transferred after a while?

My wallet has 6 different blocks of credits (+ sign) and each one has a long string under the "Description" field.  I left my portable hard drive while traveling last week and got it sent back to me.  Is there a way I can back up my bitcoin info in case I ever lose my portable drive in the future?

Thanks!
