Thanks for trying Kris,
I too 'had another go', just after I posted my earlier reply. Last time I couldn't even get the brush to work, but this time its much better. I think it is actually evolving quite fast, but I am not sure of its viability. I took some notes, for this installation -
The first time I tried to browse some images, it crashed. seemed Ok the second time.
afaik, it doesn't do anything with raw files, nor psd. It does not like the tif files I created with cs2.
Opens jpegs OK.
Played with layers, but adjustments do not seem to work except on one background copy
It sort of looks like photoshop, but just doesn't work as I would expect it to.
When the screen first opens it looks very good, but downhill all the way from there.
If what he has mapped out worked properly, then it may be of some use, particularly for linux and other users. I may play with it some more, see If I can actually get something useful from it. However, I am very puzzled as to why anyone would release such buggy software in the first instance. Perhaps he has a reason on his site, I will poke some more.
Best wishes
