Hi,
I think I know what you mean - there is a flashplayer bug when quality is set to HIGHSHARP,
when HIGHSHARP is set, a sharpen filter was applied to the pano,
but flash sometimes has some strange rendering errors when the pano was overlay with
other elements, you can see this effect also sometimes in the editor plugin,
in Flash10, there are the movequality10/stillquality10 settings for quality, which are default set to HIGH,
I think this would be the difference in your test,
a solution at the moment would be to use only "HIGH" for stillquality,
but I'll try to find a solution/workaround for this flashplayer bug...
best regards,
Klaus
