I have been trying out mining for a few months, using Electrum as my wallet & all was well until about 5 payments ago.
I noticed a day or so ago that the last 5 were still staying "pending". I was using a slightly older version of Electrum (probably 1.7.2). At least all the transactions before this were remaining confirmed. I thought perhaps I needed to update Electrum so I did that. Nightmare, now all of the transactions (to/from all addresses in the wallet, everything) are displayed as "pending". Help! What's going on please anyone?
