I must add some suggestions regarding copy/paste several meshes on GGMax.
When you run the GGMax, the engine converts all your meshes to be compatible with, so is better to way till GGMax finishes this task, before does nothing, at least at this stage.
I myself end up uploading a mesh than do not be converted yet and obviously GGMax crashes, maybe this task is going to go for a different way, anyway, the windows that pop up should be topmost and/or modal.
