i tested muse 0.8.1 for a buddy today and tried to play
around with his .med file. Sadly it seems scrolling
vertically up and down messes up the muse display as
can be seen from the attached screenshot. Clicking
somewhere seems to cause a redraw which fixes the
display until vertical scrolling is again used.
The one thing that comes to my mind about my system
that might confuse apps is that i have backing store
enabled [an X extension to have apps render into a
buffer instead of directly to the screen].
