I am using VS 2008, SP1 on Windows XP and have created a custom forms designer which works well for my user controls. I have created a simple glyph to paint a border around those controls.

For some reason, the GetHitTest method is not called when the mouse is over the control. Instead, it is called when my mouse is outside the design surface client area. Other glyphs/behaviors provided by Windows Forms, such as selecting or moving controls, works fine.

Whenever "GetHitTest" is called on my glyph, the mouse is outside the windows forms designer area, or right on the edge. Why would that be?

Glad to provide more info as needed. Thanks in advance!
