ok, I´ve done your test.
I worked with my file, 320 Sites, 900 kb only text. In this book I have 21 chapters which I have formatted with three different master pages.
So I repeated my work and formatted them all new.
The first 100 pages it works and then while procceding the used working memory grew, to 4 GB RAM, to 6 GB an then until 10.5 GB RAM. My machine did not crashed because a had made an upgrate to 16 GM RAM. But my task-manager shows me alarming red 95% usage - for there are other processes in my working memory, you know.
result: the same problem - not better.
And by the way, the text lineal is also not visible.
Is it not visible, because all my textframes are formatted with master pages? But I need a text lineal there to format the tab stops
be blessed! Alex
