Zoom 100%

[psss]

I use Scribus for the first time.
I make a little book A5 with 85 pages with text and photos.
Everything is OK except one problem  : 
I can work with a zoom 100% only on the page number 1 to number 25.
To reach the last page I must put a zoom 55% and I cannot work on the last pages with a bigger zoom.
Do you know what is possible to make to work on all the pages with zoom 100% ?
Thank you for your answer

There was a thread about this before. If you're using Mac OS X, then take a look here, seems to be a known bug.

Yes, I use Mac OS 10.6
Thank you for your answer

I worked with Scribus 1.4.0rc3.
Now I work with Scribus 1.4.0 rc5 and  I have no problem with zoom.
Thank you for the persons who repaired the bug
