ActionBarSherlock disappears when focus changes from EditText to Button

I have a simple login layout containing two EditText fields and a button to login. The problem is the ActionBar disappears when the soft keyboard is open and I change focus from the EditText to the button and the ActionBar comes back again when I click. The problem does not occur when the soft keyboard is closed and I navigate through EditTexts and Button using DPAD.

I am using ActionBarSherlock and the problem only occurs on Android 2.x emulators, on 4.x emulators everything is fine. I know ActionBarSherlock uses native ActionBar versions in Android versions where it is available, so this is probably a problem with the ActionBarSherlock code.

I also ran a test to check the value ActionBar.isShowing()

, but this returned even when the ActionBar was not visible on the screen.

I can't figure out what's going on in this case, does anyone have any ideas?
