Node type: geth
OS: osx
Network type: main
Mist version: 0.7.4
I've upgraded by Ethereum-Wallet OSX app from 0.7.2 to 0.7.4, right after making a successful transaction. I tried making another transaction, copy pasting the exact same password I've used before (both were copied from a clipboard manager, so they're exactly the same). In 0.7.4 I get the "Wrong Password" message.
I've checked the node.log file, nothing related there.
The console says Error: Transaction denied, with a bunch of network errors connecting to cryptocompare.com (which I really hope aren't related). Here's a screenshot:

I went back to 0.7.2 and re-tested-- it works fine there. It got broken somewhere between (0.7.2 and 0.7.4].
Might be worth noting my password contains some special characters including: $%&.
Would love to further assist in resolving this issue.
