With modules you can have a module-wide singleton or an application-wide singleton depending on whether you import the singleton class also in the main application or not. I’ve written a post on my blog about this that demonstrates the different behaviors. I think it could be useful to avoid strange behaviors of the singletons in each modular Flex application.

Line1: import mx.managers.DragManager;
Line2: private var dummy:DragManager;

[...] This bug is created because you have more instance of DragManager in this sample, but DragManager in Flex framework is used like a Singleton so only one instance per time. See the rest here: Modules and DragManager bug in Flex 3 « flash platform! {desktop … [...]

Good find and thanks! I had run into that very issue awhile back never really finding the culprit and finally the UX changed such that it was no longer an issue. Guess I dodged a bullet back then.
