    Hey guys, I'm working on a program that uses an NSOpenpanel to select and load a file. Thing is though, it's working kinda slow. In the console, it shows me:

    Debugging it shows that this is happening while the NSOpenpanel is loading and becoming visible. I've never had an app show that it's switching to the same process repeatedly, so I'm wondering if this is what's making it slow, and if it's supposed to happen.

    Same thing happens to me. I don't think its a problem. doesn't seem to slow down the program at all

    Any I/O is going to cause a task switch, so I would guess that the File I/O would be switching back/forth from your main thread.

    Just a guess...
