Ed says:

	If you are running under Gtk, that will be greyed out due to a  
limitation of Gtk: one modal form cannot create a second modal form.  
You'll have to create the connection first.

But I can't reproduce this finding with this code:

import dabo
app = dabo.dApp(MainFormClass=None)
app.setup()

dlg1 = dabo.ui.dDialog()
but_dlg1 = dabo.ui.dButton(dlg1, Caption="launch 2nd modal form")
dlg1.Sizer.append(but_dlg1)

def onHit_but_dlg1(evt):
	dlg2 = dabo.ui.dDialog(dlg1, Caption="2nd modal form")
	dlg2.show()

but_dlg1.bindEvent(dabo.dEvents.Hit, onHit_but_dlg1)

dlg1.show()
