I too have experienced some mysterious crashes. I'm using Spotlight 9.5.1 w/RenderWorks on a G3 Powerbook (firewire version) with 320MB ram and OSX 10.1.4. It is not as frequent as some have listed but enough to be quite frustrating. In addition to the crashes I'm having a couple of wierd things I didn't see on the lists. The first on is a problem with screen redraws. I have drawings of 3-D objects in front, right, left, top and isometric views (each on a different layer) . many times when I change a view for one layer I get the other layers redrawn over the top of the active layer object. The only way I've found to fix it is to go back through the layers, change the view to top/plan view, restore it to the appropriate view for the layer and rerender - repeating for eadh layer. The other problem is the data display bar goes invisible from time to time. Any ideas?
