Hi All,
I've encountered this problem with the both NavigationToolbar2Wx and the
NavigationToolbar2WxAgg.
When I click the Zoom or Pan button the button disappears. The functionality is
maintained so if a click the location that the button used to be displayed at
the toggle action still works its just that the button is no longer displayed.
Can any one help me fix this?
Thanks
David
