Andrew,

And you are using the native VFP combobox? A cbo droplist normally does scroll as you drag the thumb. It does for me in the quick test I just ran.

Is it set to Style=DropDown List? If IncrementalSearch is set .t. the user can type and seek values. The keys need to be set to typed within _DBLCLICK seconds so a lot of us have custom code in the lowest level cbo subclass GotFocus() and LostFocus() that temporarily increases _DBLCLICK.

I won't be able to reply again till Wed. For the others to help you debug this, post the overridden properties and maybe any method code you have in the cbo, it's definately not acting like it's supposed to.

>I'm sorry I didn't describe my problem more clearly, let me try to do that now. It is the Thumb (now I know what it's called) that I am having problems with. While I'm moving the Thumb the List appears to be frozen, only reflecting the change in the Thumb's position when I release the mouse button, in other words when I let go of the Thumb.
>For example: suppose the list contains names, sorted alphabeticaly. If you want to look someone up whose name starts with a 'j' but the visible part of the List points to names that start with an 'a', you can do that quickly by jumping into the 'j' neighbourhood by using the Thumb, so long that you get an immediate visual feedback of how far down you reached in the List. Well this is what isn't happening. Without this feature, using the Thumb is like searching blind, not knowing which part of the List will be displayed when you are done. I do get the proper visual feedback by scrolling through the List with the arrows, but it is a large list I am dealing with and searching this way is a very slow process.
>Well, I hope this time I was a bit clearer and I would really appreciate if you could throw in any suggestions.
