Yes, but you use it totally differently. for example, the sample app creates a new service stance for each call. your app (when i looked at it the first time) does not, and it uses async calls. My guess is that what you are seeing now is a totally unrelated bug (might still be in RO, might be in how you use it), because what caused the original problem was fixed by the change i made (and i say that not just based on "it worked after" but based on that the code had a logical problem with how it resumed the background thread, and that problem was fixed).
Can you at all reproduce the problem with a variant of the original Xcode project?
If not, i can debug your Oxygen project, but not until next week, as i'm afraid i'm off on vacation(ish), tis week...
