After some time i have realized that pp in information window is based on the same number as in inventory window capacity.
When i log in it is 750.00 - same as mine max capacity is, my gues - because it wasn\'t refreshed.
It may be refreshed when you, for example kill a mob, but it dont always have to.
When it refresh pp in information window, then it is the same number as your current capacity, not max. I have asked someone else and he saw the same conection.
I dont know if that was known, but i though it would be good to tell about it.
