In the current "stable" version the "pot odds as %" checkbox does not work. If you check it and close the window, the box is unchecked again. I have then tried some beta versions: 68XX and also the latest 6948. The checkbox now works (it remains checked) but the odds are still displayed in the "X:1" format, and not as percentages.
I looked in the Config/prefs.xml file, and noticed odds_percent2="False", but setting it to True does not make a difference. I am hoping this gets fixed soon, as I'm not that fluent with non-percentage pot-odds. As I programmer I doubt that it's more than 15 minutes work.
I justed wanted to say that this bug still exists in the latest beta, and it's an important feature to me.
Thank you for listening
