Hi, Kevin-

It's certainly an issue with zorder. I worked around it by moving the invisible container off screen, like so:

WITH this.parent.container1
	.visible = .t.
	.left = thisform.listboxleft
	.top = thisform.listboxtop
ENDWITH
WITH this.parent.container2
	.visible = .f.
	.left = -10000
	.top = -10000
ENDWITH

>You need to populate the two list boxes with records, then just run up the form and attempt to click/select a record from the focused list box, and you should get either a delayed response or none at all. The records can be selected using the keyboard ok though.

>Hope that helps.
