The List COMP’s “inside” panel value shows as 0 when the mouse is over the scrollbars. Is it supposed to be 1 since the mouse is still over the list COMP’s area?
You can work around it by wrapping the List COMP in a Container COMP of the same size and looking at its panel values.
This should be fixed in 60440, in that inside will be 1 if mouse is over any part of the List COMP. Thanks for the bug report.
