Please fix the bug

Im an iphone 4 user with 4.0.2 firmware. After I upgrade to 3.3.4, whenever I hit home button during reading, it will be in landscape mode the next time I open the app to keep reading! There is no way to change it back to portrait mode during the reading again. It will stay landscape forever even if i quit the app and reopen. Please fix!

Update: the 3.3.5 update still doesnt fix the bug! Please fix the bug!!!
