Mission Control bug?

I have 5 different desktops open with certain apps on different desktops. In Snow Leopard those apps would stay on that desktop even when closing the app or restarting the mac. But now its all changed when i re-open an app because i've had to close it, it doesn't default to the right desktop. This becomes really frustrating when i have to re start my mac and all my apps open on one desktop instead of the ones i set them to.

Is it supposed to be like that or am i missing something really obvious?

Thanks

 

When i try that the option is greyed out :/ It just gives me All or none as an option.

Ah, i think i've done it! You where right, i had to go to each app and assign to "this desktop"

Thanks! It's a shame they have made you have to do this though!

 

haha, i don't really know. It's just kind of happened over the last year. I have my calendar and adress book on one then safari on another and iTunes on another, etc etc.

Works well for me i guess
