I have a base maintenance form that has a only a single GradientFormHeader and ToolStripContainer controls. Very sporadically the MaintenanceFormToolStrip disappears at runtime from my forms, and when I check the line below has been deleted from the designer file and I have to add it, then it is OK for a while. Any ideas?

Me.ToolStripContainer1.TopToolStripPanel.Controls.Add(Me.MaintenanceFormToolStrip1)

So it looks like this:

MYBASE - Inherits MicroFour.StrataFrame.UI.Windows.Forms.StandardForm

MYMAINTBASE - Inherits MMYBASE

frmSomething - Inherits MYMAINTBASE (funky behavior described above)
