I have ethereum wallet 0.8.1 and was trying to send ether. But the transactions get stuck in the wallet. They go into the queue at the bottom but the transactions never show up in the blockchain explorer. When I get to look up the transaction in the block chain explorer it indicates, "Unable to locate Transaction entry". Note that my blockchain is out of date and will probably take a couple of days to update. I do see a connection to several peers though. My questions:
--Any idea why this might be happening? Is it because my blockchain is not up to date?
--Do I need to be concerned those transactions will spontaneously go through at some point?
Is there a better place to post these questions?
