Space in indexes between numbers and titles

[Emanuele Gissi & Alessia Franceschi]

Hi,

I have got a little problem: at the end of my document both chapter numbers and
figure numbers have 2 digits, as in chapter 15 figure 37. In the "List of
figures" the figure captions almost overlap their numbers (example 15.37).
I attach the PS file to better explain the result.
How to convince the caption to leave some more place to the 4 digits?

Thanks a lot, Emanuele.
