strange door behavior

[macfrog]

hi.
i just want to tell anybody who is interested in my off-topic memory issue the following:
i've finally managed to find the reason for that hungryness of sh3d in my case, it's the texture use for greater detailed objects, such as windows (e.g. patioglassdoorunit) and benches, chairs etc., as been already suggested by hansmex (thanxs for that). so far i removed all remaining textures and my sh3d is now again able of rendering (even its still on the edge 75MiBs free).
