I have implemented landscape support in my application and it worked just fine with the S60 FP3 BETA SDK. However, when I tried it under the final S60 FP3 SDK, the app crashes in the call to CQuickWordAppUi::HandleResourceChangeL().
Has anyone else seen this? All I do to change the orientation is call SetOrientationL(EAppUiOrientationLandscape) which in turn calls the HandleResourceChangeL() and then after that I draw my control in the new client rectangle. ANd as I mentioned, it works just fine in the BETA SDK.
