>Have run into occasions where on some computers, comboboxes and dropdown lists don't function quite right. In particular if you use a mouse, you can click on the control, the list does appear, but clicking on an item in the list does not make a selection when you click on a list item (i.e. the list is dismissed w/o making a selection). On the other hand, if you use the keyboard you can indeed make a selection. Does anybody have an idea of what may be causing this issue ?

It's the bug - maybe: http://www.baiyujia.com/vfpdocuments/f_vfp9fix60.asp
