Looks like I found a PoS block last night.
Strange that the wallet does not correctly compute the PoS reward and shows 0.00 instead. Added to TODO. (Or does it after the stake matures?)
Also, thumbs up for using client with Yak logo.

"Recent transactions" should show PoS reward. Coins were returned to same address but with PoS reward added so balance was increased, not 0.0
