And you have Bitcoin open and running on your computer?
Is Bitcoin able to connect or is it stuck at 0 connections?
From the description on the mouseover, it sounds like all this means is that you didn't spend those coins yet.
Yes, there were more than 110 Connections (on the sending pc and also on the receiver pc) when I processed the transfer. Both were running on MAC and Ubuntu with standard bitcoin client software (running for another ~3 hours after sending).
Yes, there were def. more than 100,000 blocks. I am a new user with bitcoin but I have 5 transactions (3 receivings, 2 sendings) on my account, without any problems. And now (with number 6) it's pending for such a long time.
