I'm quite new here.
I have a problem with the new iOS 5.1 slide-in popover in UISplitView.
(Before 5.1 the master view controller was presented in a popover, but now it simply slides in form the left.)
When my device is in portrait mode and it receives a memory warning, the master view controller unloads; and when I press the toolbar button to slide in the master view, it loads again.
However after the memory warning it is presented in fullscreen and not only the size of the original master view. (When I rotate the device to landscape and back to portrait, it gets its correct size back.)

Before iOS 5.1 it was always presented in the popover with the correct size.

Anyone has an idea, how to correct this?

I've tried to set the master view's frame size, but it doesn't solve the problem.

Any help is much appreciated!
