And I have this line in the pano
this looks very much like a memory/flashplayer bug,
that's nothing what can happen from actionscript coding itself...
EDIT: forgot what I wrote
I can reproduce this bug now, it was because of the not finished multiresolution loading / memory managment code in this version. but there is also a bug in the flashplayer! it shouldn't crash in such situation.
it will be fixed in the final version anyway!
