Hi there,

Same here.  1 transaction stuck for around 24 hours.  Seems like btc unconfirmed transactions are particularaly backed up at the moment (69k as I write, up from about 24k yesterday).  I've enabled manual fees on my wallet now for all future transactions.

Been trying to find the answer to this one on the web but not having much luck.

Is there a time limit in which if the transaction is still unconfirmed, the transaction will be cancelled (like a 48 hours limit or anything)? 

Cheers

Dave
