My first question is how do you access the Inventory now? The only thing I seem to be able to do is utilize the quick menu.

My second question is, is there a way to increase the time the quick menu items stay open? Every time I try and utilize the quick menu it downsized before I can press the needed next key.

Third, When I loaded my save game for the Foundations update, it was not my last save game. I was not on the planet I last saved on (I was on a space station, in a different system). It was not my ship, it was one I replaced months ago (Months of saving up). Did anyone else have this happen?

I use the games original method 'Tab' to get to the menu's (and 'Esc' to get to the game menus), this still works in Foundation.

Have you re-mapped the keyboard controls perhaps?
