Many of the things noted above are annoying, but we should not lose sight of the fact people have spent time and effort making this stuff, and been good enough to offer it for free. One way to avoid the frustrations inherent in using free stuff is don't use it, make your own props textures and figures ;) No one is forcing any one to use their imperfect free gifts. This is not meant as a shot at any of you, just a statement of fact.
