I am not really familiar with this kind of client, but I just send 1 coin to myself and wait for 1440+ confirm, then click on forging, and there is now green light with Forging.
I can see 2 forged blocks, but amount of both is 0. My client (java+open browser) is turned on all the time.
The two blocks you forged probably didn't have any transactions inside! I've had a few like that so far with 0 transactions and 0 fees, I got lucky and hit on one that had 3,000nfd as a fee
Since the network is still quite young and there aren't too many transactions at the moment, we should all be making some small transactions or messages to ourselves to step up transaction volume (and some fees) in our growing network as well as encourage forging for a healthy network. A few coins here and there as fees isn't much, and it would encourage people to forge as well as improve network strength. (Even seeing 1 coin as a forging reward is better than 0...)
