Thanks, I think, for letting me know :-)
Blobs do not take into account any transformations; I just never thought of it. Duh.
The class keeps track of all instances, deleting them when #delete is sent, but when a blob is in a transformation morph #delete is never sent so the blob is remembered as if it still was visible. I haven't found a way today to tell, for sure, when a morph is deleted.
I also have found no way to turn off transformations from the halo, an alternative I considered along the way today.
Where translucence goes is a mystery; I suspect a bug in the TransformationMorph but I haven't looked yet.
Anyone have any suggestions? My wife is just finishing up home made Quiche Loraine and that rates ahead of bugs any day...
Thanks,
Dave
