[Message part 1 (text/plain, inline)]

Hi again,

I decided to reimplement Mustafas ideas in a 10.6.8 compatible manner, and
to address the problem with the image being covered by scroll bars I
mentioned before. In addition, my implementation is aware that several
bell:s may be active at once and won't remove the image until the last one
times out, which eliminated flickering.

Unless anyone objects, I will publish this in the beginning of next week.

Sincerely,
    Anders Lindgren
