Are we sure the Delete key doesn't work?
Keep in mind that Poser 7 stores every action in its "undo" buffer. If the object is large enough, it will seem like Poser is "hanging" as it tries to remove the object.
 
Has anyone actually done any kind of testing to see what effect this buffer has on Poser's speed? Will Poser start to slow down significantly if you've deleted multiple V4 figures (for example) while working on your scene?
