Game crashes sometimes when char changes weapon

Greetings, Grinding Gear Games Staff.

I recently played Path Of Exile in last Public Stress Test and I liked very much. It is a light and beautiful game, and I remembered when I played Diablo 2.

However, I had some problems: sometimes, in battle, when I changed weapon pressing X key, the game crashes, and Windows showed its illegal operation window.

My notebook: CPU Intel Core i5, 8GB RAM, Intel HD Graphics 3000, Windows 7 64-bits Ultimate.

Thanks for attention.
