This number represents the number of dialogs that can be held in the cache, which is used to speed up access to dialog boxes. Valid entries are 0, 1, 2, and 3. The higher this number, the more system resources used by TRAFFIX™. If your system tends to crash when opening dialog boxes, try a lower number for this preference entry. Users with relatively fast computers (Pentium IIIs or newer) can generally use 0 (zero) for this setting.
