NewStory: crash when fast-scrolling history-rich contact

[Mitch037]

1. open contact's history (it has to contain at least 5000 events)
2. maximize the window
3. start rapidly fast-scrolling by holding the scroll bar and moving it up&down from one end to the other
4. after a few seconds Miranda crashes
