Debugging on Mavericks

I have endless problems with debugging and it's super frustrating. First of all the attach to process dialog keeps accumulating these (null) processes which means you have to scroll down to find the editor. When you do you can't simply click on it -- oh no it refreshes or something in the background. If I'm lucky it will attach to the process. Now lets say I stop the game in the editor do a few enhancements to the scene and then run it again it hangs. I can record a video of my experiences if this helps. Am I the only one or is there help / workarounds out there.
