Redynamix Previews

[glip]

Hi:
I just started to use Redynamix, running it as a plug-in to Irfanview under Win XP. I have a question about the preview option buttons that appear below the display (<quick> <fine> and <full>): do they do anything? I would have assumed that <fine> and/or <full> would have yielded a larger display to check the quality of the processing, but that's not the case.

Thanks for you input.

So, does anyone know? Not looking for anything deep, just trying to find out how I can get a larger preview to check the adjustments being made.
