The only issue I have is that pressing O while inside a menu while spawning, cancels spawning.
Same with opening the player list with D-Pad Down and then closing it again when I just want to scroll down the list.

Other than that, I have never yet had any UI problems where it opens after closing. Don't mash buttons like ADHD children. If you press it, the game will do it, just wait a second.

The whole button layout is very intuitive and convenient. I've not had any problems whatsoever with doing things since every situation has a button tooltip explanation if you wait a moment and look at the screen before mashing your face against the controller.

To clarify, i'm not sat here like im plating Chariots of Fire....... But deep in a vehicle mod screen im not gonna press circle once, wait for it to exit that, then press it again etc etc etc...... Most people at this point will just do circle 3 or 4 times at once to escape it asap,,, and if you press it too often still within menu screen, it'll still register it after,,, all i'm suggesting is a method to prevent that, as this is a common way of dealing with PS3 menus....
