Why does windows keep scrolling my listview

[johnman]

I've made a little configuration dialog with a listview and i noticed that when i select the lowest item from it (which is only partly visible) the listview automatically scrolls a little to make it fully visible.

I also noticed that when i select an item, and scroll down very fast, windows lets the listview scroll up again to make sure the selected item is visible.

This is VERY annoying, so i decided to block the WM_TIMERS to the listview, which seemed to solve the problem.

SO i got two questions:

a) why does windows keep scrolling MY listview? How can i turn this of? (besdides blocking the WM_TIMER)

b) why does windows keep sending WM_TIMER's to it? Can i just block them without any bad side-effects?

EDIT im using winXP
