Unfortunately this is so. You need to properly set Visible property for each ActiveX control when container's Visible property is changed.

To do so automatically I use my own ContainerX class which is sublclass of Container base class.

Visible_assign method:

LPARAMETERS vNewVal

LOCAL oldLock
m.oldLock = THISFORM.LOCKSCREEN
THISFORM.LOCKSCREEN = .T.


* Óñòàíîâêà Visible ïåðåä îñòàëüíûìè
IF m.vNewVal THEN
  THIS.VISIBLE = .T.
  THIS.SETALL("Visible", .F.)
ENDIF

THIS.SETALL("Visible", m.vNewVal)

IF NOT m.vNewVal THEN
  THIS.VISIBLE = .F.
ENDIF

THISFORM.LOCKSCREEN = m.oldLock

Init method:

This.visible_assign(This.Visible)
