activation show view option

[BIAGIO]

Hello, everyone.
I was modeling a set with inventor 2010.
in the window of the bond options I realized that "show preview", it is not possible to activate it with the check mark.
for which the assembly is still carried out, but to view the effect of the bond I must click on update.
Can you tell me what the problem is?
Thank you all.

We talked about it here: http://www.cad3d.it/forum1/showthread.php?t=16506is native therefore forgive you, but there is a " search " function that would give you the answer in 0.06 seconds ( search key " preview ", forum " inventor ").

Bye.
