I cannot stand this any longer. I know I'm not the only one that's been seeing crates floating around and then shot them and it does nothing! So I waste a shot and how am I supposed to know when a crate is legit or not? It's very annoying!
Crates are always legit unless one is gotten while you are in a different tab. So if you want to be sure that all the crates are legit then don't go to different tabs while playing.
Another thing is to have the windows side by side, but have the ssl2 windows like really small. You can maximize the window when you feel like it. Very simple thing and it works I think.
