the inventory and the fight

I dont know if exist a patch what fix this bug. I mean, that if you go to inventory while fighting you dont lost action points. So for example you can throw as many granades as you have in one round. Some people make Arcanum easier when they using this bug. I want to prevent that kind of actions in my mod. At least it seems to be easyer to fix inventory bug, than corner bug.

PS: Corner bug - I mean, when you figting and you will stay in the cornenr like that:
e
n |
e |
m|
y |
X |_____________
you Y
enemy just do nothing, and let you kill him/her/it very easy.
