DropShadowFilter on Air for Android

Hi all,

Is there a known issue with publishing air applications to android that use filters (i.e. DropShadowFilter, BlurFilter) ? As when I try publishing to my phone, the movieclips in question do not even render to the stage, which is strange considering they work fine when I preview them as an SWF on my computer. I've tried applying the filters in the CS5 library, and doing it using code in my document classes and neither seems to work! I've obviously tried with cacheAsBitmap(Matrix) both on and off as well.

Just wondering if its something that isn't supported? Or if there's a way round it?

Thanks.
