Too tight "OO" vs "oo"?

[usted]

Hi there
First of all great tool!

I have found that the spacing og the uppercase "O" is almost identical to the lowercase "o", no matter what parameters I use. And therefore looks a bit too tight. Is that something you have experienced before and do you have a solution for it?

My parameters are: paramArea:330 and paramDepth: 15

Thanks,
Andreas
