Hi, Thanks very much for the response.
Good idea about the awakeFromNib, but I changed my test app to use a button instead and both problems remain (the flipping, and the disappearing sublayer. The application I am using this in is not much complicated in principle than the example app, other than the layers are a lot prettier :-) My app is basically a hierarchy of layers in a scrollview (although the flipping issue appears to be an NSTabView problem, as it still happens outside of a scrollview). I used to use a simple drawRect: based drawing system, but is was slow, so I'm trying to move to Core Animation, which has certainly sped it up, but I've still got a few issues to clear up.... Does anyone have experience with Tech Support Incidents? I'm thinking about springing for one of those.
