Robert,
I reproduced the problem what you mentioned, here is a workaround for you, please put these initialize code to the Form_Load event, that is the same implemention as you set it in the design layout, here is the code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.WinformsMap1.BackColor = System.Drawing.Color.White
Me.WinformsMap1.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighSpeed
Me.WinformsMap1.CurrentScale = 4000.0R
Me.WinformsMap1.DrawingQuality = ThinkGeo.MapSuite.Core.DrawingQuality.HighQuality
Me.WinformsMap1.Location = New System.Drawing.Point(6, 35)
Me.WinformsMap1.MapFocusMode = ThinkGeo.MapSuite.DesktopEdition.MapFocusMode.[Default]
Me.WinformsMap1.MapResizeMode = ThinkGeo.MapSuite.Core.MapResizeMode.PreserveScale
Me.WinformsMap1.MapUnit = ThinkGeo.MapSuite.Core.GeographyUnit.DecimalDegree
Me.WinformsMap1.MaximumScale = 4000.0R
Me.WinformsMap1.MinimumScale = 100.0R
Me.WinformsMap1.Name = "WinformsMap1"
Me.WinformsMap1.Size = New System.Drawing.Size(519, 365)
Me.WinformsMap1.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed
Me.WinformsMap1.TabIndex = 7
Me.WinformsMap1.Text = "WinformsMap1"
Me.WinformsMap1.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias
Me.WinformsMap1.ThreadingMode = ThinkGeo.MapSuite.DesktopEdition.MapThreadingMode.SingleThreaded
Me.WinformsMap1.ZoomLevelSnapping = ThinkGeo.MapSuite.DesktopEdition.ZoomLevelSnappingMode.None
End Sub
Please try the workaround in your application again, Any more questions please let me know,
Thanks,
Scott,
