Getting this error message: Object reference not set to an instance of an object.

[Freddy]

 

 

while on the “game select play” screen and trying to exit BigBox with an X (sent from an AHK script outside of BB/LB), I’m getting a crash….

(basically I have a “fakesleep” button that closes LB and then closes the game and then turns off computer screen …

I wanted to exit LB/BB gracefully so it would do any cleanup….so i hide the game window, then click on BB and then send it the X key and then later kill the game)

The BigBox “game select play” screen is actually still there, sort of, but all the menu selection options are gone, yet

the star ratings, play count and game title are still there…crash window pops up

this only seems to happen when running games that take control of screen aggressively

many games never crash….and even the crashing games only crash sometimes but quite often

message screen attached below:

anybody any ideas on how I can fix ?

thanks

Freddy

[Freddy]

Turns out that if I send a back command, and move to a different screen in BigBox, then send the X to exit.....no Bigbox crash

no idea why..

hopefully, this helps out someone else...took a while to figure out this work around...but it works just fine now.
