Strange Label Behavior

A Form has 3 Labels. I want the 3rd Label to look like a hyperlink (clicking the 3rd Label opens another Form). Since I want the 3rd Label to look like a hyperlink, I have even made the cursor change to a hand & the Label underlined when the mouse is moved over the 3rd Label. The hand cursor resides in a resource file. This is the MouseMove event function of the 3rd Label:

Code:

---

Private Sub Label3_MouseMove(Button As Integer, Shift As Integer, x As Single, y As Single)
    Label3.FontUnderline = True
    Label3.ForeColor = vbBlue
    Label3.MouseIcon = LoadResPicture("Hand", vbResCursor)
    Label3.MousePointer = vbCustom
End Sub

---

Since users can change the back color of the Form on which these 3 Labels reside, I have set the BackStyle property of all the 3 Labels to Transparent (at design time in the Properties window) but what I find is when the mouse is moved over the 3rd Label, the font of the 1st & 2nd Label becomes bold. If I set the BackStyle of the 3rd Label to Opaque, then this problem doesn't arise. The font of the 1st & 2nd Label becomes bold only when the BackStyle of the 3rd Label is set to Transparent & the mouse is moved over the 3rd Label.

How do I overcome this?

Well I could overcome the problem by replacing the 3rd Label with a TextBox but would still like to know why was the transparency of the 3rd Label affecting the font-weight of the 1st 2 Labels when the mouse was moved over the 3rd Label?

I have no idea why you have this problem, it shouldn't happen. However may I suggest replacing all three labels (if they are grouped together) with one HyperLabel control instead? To get the transparant background set the Visible property to False and the RenderToContainer property to True.
