Thank for advise, will look into using the
debugger to trace the events.

This can not show the problem because
events time domain change when the debugger is open.

Try this little trick:

* add one or both
thisform.lockscreen = .T.
this.visible = .F.
* now the VFP Paint engine can read a invisible status for the command
THISFORM.pfgMain.PgWelcome.Zorder
THISFORM.pfgMain.PgWelcome.Refresh
this.visible = .T.
thisform.lockscreen = .F.
