Yes, I also have seen this sometimes when special kinds of alphachannel
(flattened/premultiplied/postmultiplied) were used in the PNG to import.
Nevertheless the following 'standard' import script works for me nearly
always in LC 6/7/8/9:
on mouseUp
set the paintcompression to RLE
if there is no img "import" then create img "import"
-- handles alphachannel clever, even creates sometimes its own:
set the resizequality of img "import" to "best"
put "Select a file to import" into prmpt
answer file prmpt titled prmpt -- avoid mac 10.12 bug
if it is empty then exit mouseUp
put URL("binfile:" & it) into img "import"
-- don't "hide" my click region with transpareny:
set topleft of img "import" to the bottomleft of me
end mouseUp
