Control does not work in a class library...

Hi All,

I built my own signature control with save and load functionality.
In a Windows based application, everything works fine.

When I put my class into a class library, I'm still able to create my
control as follows:
SigC = New SignatureControl(Me, pnlSignArea, "\SDMMC Disk")

The constructor executes without problems, but in the case of a class
library, the panel (pnlSignArea) doesn't react anymore to the mouse events:
Protected Overrides Sub OnPaint(ByVal e As
System.Windows.Forms.PaintEventArgs)
Protected Overrides Sub OnMouseMove(ByVal e As
System.Windows.Forms.MouseEventArgs)
Protected Overrides Sub OnMouseDown(ByVal e As
System.Windows.Forms.MouseEventArgs)

Any help would be really appreciated,
