Why would you allow the character menu to be opened while transformed?

> Basically, my line of thinking is this: Transformation has been a breeding ground for bugs. By limiting functionality to only what's essential, there's less chance for breakage.

That's a perfect valid reason to disallow character points being spent while being transformed isn't it?
Also I personally really like the vision of being very inflexible while being transformed. I mean you could be any creature, so why allow changing essential stats of your human like behavior?
