I took the time looking over my stuff and noticed (once again) that preloaders not always work how they should do.

Some start late some may even work some don't work at all... if with api or not ...
I mean I put them in the first frame and sometimes it works but often not. Is there a special trick about it?
I would like to go on using NG preloaders, but don't know if it makes sense when never know if they work or not. . . |:-?
