White screen appears on HTC Hero when I use AndEngine
===

There's problem with HTC Hero and AndEngine's `BaseGameActivity`: when launched, there's only white screen, without any graphics like background and sprites. But I can see objects like lines (`org.anddev.andengine.entity.primitive.Line`) etc. and also I can tap on invisible buttons and my code is performing, but it's still white screen.

When I'm launch this app on other devices everything is ok.

Where is the problem?
