--- Comment #16 from Roland Baudin roland65@free.fr --- Yes, it works very well. However, I've seen some minor issues. For example, from time to time (but rarely) the brush becomes unusable. Perhaps it happens when you add many brush areas, but I'm not sure about this.
Also, there are some glitches with the black and white preview mode that helps setting the black and white points. Sometimes it interacts unexpectedly with other controls, but it's not a real problem.
Anyway, the program is fast and very usable. I hope Wine devs will integrate these patches upstream very soon (I'm not the author). RB
