Hi.
I have been playing a bit these last days with ChaosPro 4.0.249 (the last published version, from 2011).
First, I would like to know if there is a portable version of this program (I know that very very old versions were portable). In addition to needing installation, the program uses a folder in user\appdata\roaming to keep the formulas, palettes, parameters and even saved images.
Second question is to know if the programmer is still around and could fix bugs or answer questions.
I found a bug the hard way in the jobs render. I was doing a render at 3840*2160. It tooks 18 hours (the estimated remaining time lied all the time) and when it finished, it closed the program without saving the image. I have made tests with different parameters and sizes. In my tests it never saves the rendered image, but it doesn't always crashes. Is there some way to fix this? I am using Windows 10.
Btw, I repeated that render that took 18 hours using the render in window and it took only 2 hours and a half, without problems.
Thanks for reading.
