This is something that have annoyed me since i changed to Windows 7.

I don't do double click for a long time now since windows introduced 1 click selection (Folder Options > Click items as follows > Single click to open an item).

The problem is, when i click Control and hover over the items, they select/deselect automatically every small amount of mouse movement i make.

What i want is to select/deselect the items only when i enter/exit them. So to deselect an item im hovering, i have to move the mouse out of it, and then back in.

I'm using Intellimouse Explorer official drivers.

Here's another related annoyance: When you are hovering something and move the mouse inside other item (Holding Ctrl) The new item may or may not be selected. If you continue moving the mouse it gets selected/deselected as you move.

I have found that the parameter HKCU\Control Panel\Mouse\MouseHoverHeight / MouseHoverWidth have some influence here. If it's set to 2, the item select/deselect really quickly as you move the mouse. When set to larger numbers, its slower. But setting to 20 or 200 don't seem to be much different.
