Thank Bernd, I'll give that a try. Detecting mouseClicks or other mouse related functions aren't an issue for me in this case - it's that printing images with transparency on Windows can really come out strange and in some cases cause printing to fail.

Hi Marty,

would it help if the transparent parts where just a little non-transparent?
hardly noticeble

You would set all 0 to 1 in alphaData, the rest is unchanged.

-------------------------------------------
on mouseUp
    put the alphaData of image 1 into tAlpha
    put numToByte(0) into tNull
    put numToByte(1) into tOne
    repeat for each byte anAlpha in tAlpha
       if anAlpha = tNull then
          put tOne after tCollect
       else
          put anAlpha after tCollect
       end if
    end repeat
    set the alphaData of image 1 to tCollect
end mouseUp
---------------------------------------------

this is fairly fast, works also in 7.x.x

Once you change 0 to 1 in alphaData the translucent parts of the png receive
mouseClicks etc. You must be aware of that.

Kind regards
Bernd
