'Save Alpha Channel' option not appearing in Save Image dialog

Superb tool, thanks for the continued efforts over the years. Downloaded the latest version of XNALara XPS, according to the download section (v11.0), however when clicking the 'Save image' menu item there is no option to enable alpha transparency for PNGs under Windows 8.1.

All saved PNG images contain the solid background as set in the main window. Looked through all the menu options and googled but didn't find any hidden options to enable this elsewhere. Possibly a bug?

GIF capture:

Tried a different scene/model and added a background image. Adding the background image seems to open the correct alpha transparent export checkbox dialog prompt when using the Save Image menu.

Is this expected behavior?

This is the expected behavior, if you have enabled (for example) the Bloom Effect.
It is not related to the "Background image"

BTW:
XPS 11.0 is not the latest version. The latest version is XNA Posing Studio XPS 11.1 -- Osiris Isis Edition -- release 178

Ah, thanks for the clarification.

Cheers. I downloaded the version from the core-design.com mirror here. They mustn't have updated their copy yet.
