I've had this problem for a while now but I never bothered me enough to make a post, but here it is now:

sometimes, I couldn't figure yet under what circumstances, upon exiting the application (press escape in Game, which returns false in game update) I just get a crash. No idea why, everything within the application works nice.

Any ideas what might cause this?

A memory leak somewhere in your code, most likely.

Oook... apparently I'm still too inexperienced for that to tell me anything. Could you please be more specific? I just can't remembered what I changed before this error occurred. And I don't know what actually happens when I try to stop the application.

Doesn't the OS handle de-alocating memory and that kind of stuff?

Make sure that any objects you create (via new) are properly deleted before exit.

Done, solved! Found out what I changed before the error occured.

As all inventories were created within the character create, I thought i could happily remove the if inv() in the player's update InventoryGui function.
Removing this got things back to normal again, but I do wish I could live without it....

anyway, I'm glad it's taken care of, many thanks
