Problem with freeze option

[chaosss]

Hellow I am enjoying SP3x resently and I need some help.

When I thouch "frozen thruster" with my "magic hand" during simulation, it unfreeze and move freely.
But when "frozen thruster" touched by other object, it moves during contact and it freeze again when it lose contact (with other object).
I attache file with the situation I wrote about.

Any solution with this problem? I expected "noautofreeze" option could be helpful but it dosen't. Actually I dont know the effect of the option and what is the "autofeezing".

I am sorry for my poor English.
