view command: does not keep detail, displays extensions

[graziano-g]

hi, I generated custom views with ucs after setting the ucsfollow variable to 1.
of course I have selected the necessary conditions to me: ucs, area, layer.

when I call the views, the set detail (area I defined ) appears to me for 1 second and then switch to zoom extensions, as if in some way the zoom extension command is called. . .

Any idea why?
Thank you.

in the bottom right, in the box showing the preview of the view appears all the drawing despite I have selected only a part of it... .

Where am I wrong?

found, it seems that by setting the ucsfollow variable on 1 ( defoult =0 ) you manifest the problem... .
Can anyone check?
Thank you.
