Canvas color change on mouse exit not happening

I have a number of DesktopCanvas controls acting as buttons. I indicate “button pressed” by changing colors. When users mouse down but then drag the cursor off the control before releasing, that cancels the “button press”. This works fine, but I need the button’s color to change back to “unpressed” as soon as the cursor exits the control, and it just isn’t working, only changing to “unpressed” upon releasing the mouse button. The below code uses timers for a couple different purposes, but the color change also doesn’t happen for controls that don’t use a timer.

Sub Paint(g As Graphics, areas() As Rect)
  If (Me.Name = MouseOverXY) And Not(EStop_Pressed) Then
    g.DrawingColor = Color.Blue
  Else
    g.DrawingColor = Color.White
  End If
  g.FillRoundRectangle(0, 0, g.Width, g.Height, 10, 10)

  If (Me.Name = MouseDownXY) And Not(EStop_Pressed) Then
    g.DrawingColor = Color.Green
  Else
    g.DrawingColor = Color.Orange
  End If
  g.FillRoundRectangle(3, 3, g.Width - 6, g.Height - 6, 10, 10)

  g.DrawingColor = Color.Black
  g.DrawRoundRectangle(0, 0, g.Width, g.Height, 10, 10)
  g.DrawRoundRectangle(3, 3, g.Width - 6, g.Height - 6, 10, 10)
  g.FontSize = 28
  g.DrawText("X+", 5, 32)
End Sub

Sub MouseEnter()
  If Not(EStop_Pressed) Then
    MouseOverXY = Me.Name
    Me.Refresh
  End If
End Sub

Sub MouseExit()
  'code goes here to stop movement
  MouseOverXY = ""
  Me.Refresh
End Sub

Function MouseDown(x As Integer, y As Integer) As Boolean
  If Not(EStop_Pressed) Then
    XSpeed_Going = ""
    MouseDownXY = Me.Name
    bump = True
    TimerBump.RunMode = Timer.RunModes.Single
    SimStep = 1
    TimerSim.Period = Slider_Jog_XSpeed.Value
    TimerSim.RunMode = Timer.RunModes.Multiple
    Me.Refresh
  End If
  Return True
End Function

Sub MouseUp(x As Integer, y As Integer)
  MouseDownXY = ""
  TimerBump.RunMode = Timer.RunModes.Off
  TimerSim.RunMode = Timer.RunModes.Off
  bump = False
  Me.Refresh
End Sub

Sub DragExit(obj As DragItem, action As DragItem.Types)
  MouseDownXY = ""
  MouseOverXY = ""
  Me.Refresh
  TimerBump.RunMode = Timer.RunModes.Off
End Sub

Function DragEnter(obj As DragItem, action As DragItem.Types) As Boolean
  MouseDownXY = Me.Name
  MouseOverXY = Me.Name
  Me.Refresh
  TimerBump.RunMode = Timer.RunModes.Off
End Function
