Xbox B Button

Ive noticed that at times when you are looking to get a report or do a science experiment that the B button simply stops working. The cursor is shown and indicating that the object you are querying is active, yet no reaction when you press B. Sometimes reloading the save will fix it, others you have to quit the game completely and come back in for it to 'self correct'. This also happens when trying to select an orbit and usually at the worst time possible.

It seems to me like it has to do with the objects, not the button, because sometimes they should be respond to (A) and I get the same results. The pointer changes color indicating that the game recognizes the button press but nothing happens.

I've also noticed when selecting orbits that it seems like the game is waiting for the button to be released, not pressed. At least it likes to select points on orbits I don't want when I release the button and then position the pointer there again and reselect it when you finally get it unselected...

I've had the same issue, especially right after docking. It almost always becomes completely unresponsive after docking large craft together. The only way I've been able to manage is to either mash the B button repeatedly until I get a response to whatever part I'm trying to access, or to go to the tracking station and then return to the vessel. It is particularly debilitating when constructing a large vessel in orbit because I am unable to deactivate different engines after docking.
