Just wanted to report, I've played a couple of historical exhibitions and...
Still no freezes or crashes!!
I have yet to really put it though its paces (haven't had time) But so far so good! Graphics, 3D, widgets are working well! There are a couple of interface tweaks I might suggest, but I'll do that later. The most important thing: it has been rock solid on a PC and Win7!
Good news, I guess. Right?
