It would also not fire if the Form has no blank areas in its client area. 
 OnMouse... events are only fired when performing mouse operations directly 
on the Form's exposed client area, not on child controls inside the client 
area.

If this form17 is disabled (because another form is shown modally, for
instance) it would not get any mouse messages.

Have you placed a breakpoint on the form3.top := 2; line to verify that
it is not reached? You have to enable debug information in the project
options (or use the default debug build) for this.

Which version of Delphi are you using?  Did you actually assign FormMouseEnter() 
to the OnMouseEnter event?
