How are you determining whether the exported image has an alpha channel?

Sorry, was a bit too fast!
Just had a look in Photoshop at the resulting files and both do
have an alpha channel.
Maybe you could export the snapshot to a variable as JPEG first
and then to fiel as PNG?
I need to export to PNG as I need a lossless image. I just tried
exporting to paint as a variable and assigning the variable to the
text property of an image but the image displayed nothing. I then
exporting to paint as a file and assigned the file to the filename
property of the image and the image data displayed properly. Alas,
exporting the image as PNG to a file resulted in an image with an
alpha channel.
Maybe you were right and all exports to PNG format DO have an alpha
channel, be it necessary or not.
