I just installed Amaya on my Windows XP system. When it starts up as the
animation is playing of the 'M' moving in from the top to form part of the
'A', the screen flickers badly and at the conclusion of the animation,
some characters are blacked out. The attached .bmp file shows the screen
after the animation.
There are other times when the screen acts as described above, but I have
not replicated these situations yet.
