I had a problem a lot like this with both particles. Does it not work
yet with them?
I also had that problem when using image texture and then clicking the
first button with the little folded picture so that you can choose
preloaded images. It does not work but if you cick the file loading
button on the same line and load the pic it works. Maybe this info
will help? I have not filed a bug report on this yet, was planning to
confirm on a newer version first but if you do confirm I would like to
know so I can file the report, on the other hand I bet it is already
filed or known by now.
Best,
