I've upgraded both the clients using CRP. now both the client on laptop and my pc are the same versions. i can see the transaction on both of them but the transaction takes no confirms at all...
Just to resume.
i tried it 3 times, with smaller and bigger trades.
Sometimes the transaction doesn't appear at all, sometimes it appears on both the client but receives no confirms.
Hmmm, have you tried re-launching both clients with the "-rescan" flag...? Or have you tried "Rebuild Block Chain" on both clients...?
