stutter~ and waveform~ weirdness (bug?)

Hi all,

When I use the feature stutter~ has, that you can specify an external buffer for it to copy its contents,
it works like a charm, but, if I have a waveform~ attached to that buffer, it does not update when the content is changed. In fact it does not update at all. It is as if the buffer is empty.

EDIT: when I mean it does not Update, I mean the graphics. The buffer is in fact regularly filled with content as expected.

Another thing: if I double click on the buffer
to bring the buffer view window, it shows the correct waveform but if i grab some more signal with stutter~
it does not update. If i close and reopen it, it updates. Seems like a bug.

Can you reproduce? I am at a MacBookPro, with latest Snow Leopard and latest Max (5.1.6).
