Impossible to dismiss 'Color Options' dialog in player demo on Symbian

Steps to reproduce:

1. Launch player
2. Open clip
3. Press play
4. Press 'Color Options' button

The resulting behaviour is:

• The dialog pops up and can be manipulated
• Video continues to play even though it is mostly obscured (separate discussion about whether the decision to pause the video in this case should be left to the app, or made by the backend)
• Both softkeys are empty and cannot be tapped
• Tapping anywhere else on the screen fails to dismiss the dialog
