Some more information on this problem:
Scrolls properly in VFP5 and VFP7.
Updated component gallery with the 'vfp6gal.exe' update from MS without success.
Thank you once again.

>Sorry to repost this problem but my deadline is fast approaching for this project.
>We are having a problem with a drop down list combo box.
>When we specify that the data source is 'alias' the thumb scroll bar moves as we drag it but the data inside the list does not synchronize until we release the scroll bar.
>When we use a data source of 'values' the data does synchronize with the thumb scroll bar as it is dragged.
>In an attempt to isolate this problem we can even duplicate the scenario with the VFP 6 base form and controls.
>I did a 'help/about' and no service packs display - just a version of 06.00.8167.00.
>Thank you for any suggestions!
