Is there a good reason I should not stick with the older wallet for now (says I'm on Qt 5.3.0), since it's working just fine for me?
Looking forward to new NXT-inside wallet, that will hopefully be a little easier to install.
By all means stick with the old wallet, if it ain't broke don't fix it! : -)
Great! Reading all the problems people are having and hoping I wouldn't have to negotiate them myself

It's one thing I love about the NXT wallet: it's a one-click download and it works out of the box. If the SuperWallet does this for participating currencies it will be a great attraction.
