First of all, this is a great tool. I just finished making my first character, but I assume I'll be up till 3am building more.
One problem though: I can't seem to break skill groups. Once I increase them as a group at character creation, I cannot split them. So if I'm building a decker with skill priority C, then I can increase the cracking group only to 2, and I can't break it to increase it from there.
Again, great product.
