I wondered if it works with Entity panel models?
Does it deliver back a valid vector, so I can attach entity panels to entity panels?

Sounds weird, but I need it for displaying player models in a menu.

It won't work because the models aren't created in the "real" world. I'd use a regular level with enable_click set for the models. If you want to use entities, check the mouse coords and if the left mouse button is down...

ok. I'll post this one as improvement in the future forum
