I find that when the program first opens, it is generating a random batch of parameter sets to browse through. My older version was set to generate one hundred files, but the newer version seems to run much slower and one hundred files takes forever. Of course it also seems to be doing much more, so the trade-off is worth it.

I opened the options dialog box and re-set the random batch quantity to ten. It now finishes creating the batch very quickly and opens right up.

The problem I have that I have not solved is that the new version seems to require an enormous amount of processor time. I often have to wait for a response, because my "processor load" is at one hundred percent. Then it takes sometimes two or three "refreshes" to accept another command or mouse movement.

(Yes, I have an old school single core 2GH computer, running Windows XP.)
