Tran,
Clearly there are some little bugs in the cbo. It would be nice if the list stayed dropped, but this isn't that significant a bug IMO.
The issue of the mouse click throughs is a bigger problem and only occurs if the mouse moves into the droplist and changes the hilight position, if you keep the mouse within the scrollbar region the clicks don't fall through. Have you reported the bugs to Microsoft? If you haven't they may not know about them and if they don't know about them they can't fix them.
I can't comment on whether or not the problems have been fixed in VFP6.
>I think it’s really a bug of the combobox. You can try realizing the actions following in the “address combobox” of Microsoft Internet Explorer:
>1. Position the mouse shape on place where the Address Dropdown list will appear.
>2. Press Alt+Down arrow.
>3. Use Up or Down arrow keys to select a address. It’s normal ! You can not do this in VFP’s combobox.

>There is an other bug of the VFP’s combobox: If you click mouse 5 times on the scrollbar of the combobox’s dropdown list but when you finish your selection by Esc key: your 5 mouse click will be effect to object behind the VFP combobox’s scrollbar (if any).
